Course/Topic 3 - Java Programming - all lectures
-
In this video you will learn the introduction to Java programming. This tutorial explains the installation and usage of the Java programming language. It also contains examples for standard programming tasks.
-
In this video you will learn based on the data type of a variable, the operating system allocates memory and decides what can be stored in the reserved memory. Therefore, by assigning different data types to variables, you can store integers, decimals, or characters in these variables.
-
In this video you will learn about the control statement in java is a statement that determines whether the other statements will be executed or not. It controls the flow of a program. An 'if' statement in java determines the sequence of execution between a set of two statements.
-
In this video you will learn Looping in programming languages is a feature which facilitates the execution of a set of instructions/functions repeatedly while some condition evaluates to true. while loop: A while loop is a control flow statement that allows code to be executed repeatedly based on a given Boolean condition.
-
In this video you learn about Classes and Objects are basic concepts of Object Oriented Programming which revolve around the real life entities. A class is a user defined blueprint or prototype from which objects are created. It represents the set of properties or methods that are common to all objects of one type.
-
In this you will learn In Java, static keyword is mainly used for memory management. It can be used with variables, methods, blocks and nested classes. It is a keyword which is used to share the same variable or method of a given class. Basically, static is used for a constant variable or a method that is same for every instance of a class.
-
In this video you will learn about Array an array is a group of like-typed variables that are referred to by a common name. Arrays in Java work differently than they do in C/C++. Following are some important points about Java arrays.
-
In this video you will learn the java.util.Arrays.binarySearch(Object[] a, Object key) method searches the specified array for the specified object using the binary search algorithm. The array be sorted into ascending order according to the natural ordering of its elements prior to making this call. If it is not sorted, the results are undefined.
-
In this video, you will learn about the Java multidimensional array using 2-dimensional arrays and 3-dimensional arrays with the help of examples.
-
In this video you will learn the java.util.Arrays.sort(Object[] a, int fromIndex, int toIndex) method sorts the specified range of the specified array of objects into ascending order, according to the natural ordering of its elements. The range to be sorted extends from index fromIndex, inclusive, to index toIndex, exclusive.
-
In this video you will learn Inheritance in Java is a mechanism in which one object acquires all the properties and behaviors of a parent object. It is an important part of OOPs (Object Oriented programming system).
-
In this video you will learn more about Inheritance.
-
In this video you will learn In Java, two or more methods can have same name if they differ in parameters (different number of parameters, different types of parameters, or both). These methods are called overloaded methods and this feature is called method overloading.
-
In the last video, you will learn about inheritance. Inheritance is an OOP property that allows us to derive a new class (subclass) from an existing class (superclass). The subclass inherits the attributes and methods of the superclass.
-
In this video you will learn about t he super keyword in java is a reference variable that is used to refer parent class objects. ... Basically this form of super is used to initialize superclass variables when there is no constructor present in superclass. On the other hand, it is generally used to access the specific variable of a superclass.
-
In this video you will learn about the Java programming language, the final keyword is used in several contexts to define an entity that can only be assigned once. Once a final variable has been assigned, it always contains the same value.
-
In this video you will learn about Polymorphism, it is the ability of an object to take on many forms. The most common use of polymorphism in OOP occurs when a parent class reference is used to refer to a child class object. Any Java object that can pass more than one IS-A test is considered to be polymorphic.
-
In this video you will learn about the class which is declared with the abstract keyword is known as an abstract class in Java. It can have abstract and non-abstract methods (method with the body).
-
In this video you will learn about methods form the object's interface with the outside world; the buttons on the front of your television set, for example, are the interface between you and the electrical wiring on the other side of its plastic casing. You press the "power" button to turn the television on and off.
-
In this video you will learn the interface is a reference type in Java. It is similar to class. It is a collection of abstract methods. A class implements an interface, thereby inheriting the abstract methods of the interface.
-
In this video you will learn about the interface in Java is a mechanism to achieve abstraction. There can be only abstract methods in the Java interface, not method body. It is used to achieve abstraction and multiple inheritance in Java.
-
In this video you will learn about the main difference is methods of a Java interface are implicitly abstract and cannot have implementations. A Java abstract class can have instance methods that implements a default behavior. ... A Java class can implement multiple interfaces but it can extend only one abstract class.
-
In this video you will learn about the packages in Java is used to group related classes. Think of it as a folder in a file directory. We use packages to avoid name conflicts, and to write a better maintainable code. Built-in Packages (packages from the Java API) User-defined Packages (create your own packages)
-
In this video you will learn about the access modifier, there are four types of Java access modifiers: Private: The access level of a private modifier is only within the class. Default: The access level of a default modifier is only within the package. Protected: The access level of a protected modifier is within the package and outside the package through child class.
-
In this video you will learn about the Encapsulation in Java is a mechanism of wrapping the data (variables) and code acting on the data (methods) together as a single unit. In encapsulation, the variables of a class will be hidden from other classes, and can be accessed only through the methods of their current class.
-
In this video you will learn about the Strings in Java are Objects that are backed internally by a char array. Since arrays are immutable (cannot grow), Strings are immutable as well. Whenever a change to a String is made, an entirely new String is created. Below is the basic syntax for declaring a string in Java programming language.
-
In this video you will learn about Java String, how to create it and its various methods with the help of examples. In Java, a string is a sequence of characters. For example, "hello" is a string containing a sequence of characters 'h', 'e', 'l', 'l', and 'o'.
-
In this video you will learn about the Exception (or exceptional event) is a problem that arises during the execution of a program. When an Exception occurs the normal flow of the program is disrupted and the program/Application terminates abnormally, which is not recommended, therefore, these exceptions are to be handled.
-
In this video you will learn about the Customized Exception Handling: Java exception handling is managed via five keywords: try, catch, throw, throws, and finally. Briefly, here is how they work. Program statements that you think can raise exceptions are contained within a try block. If an exception occurs within the try block, it is thrown.
-
In this video you will learn about the Finally block contains all the crucial statements that must be executed whether exception occurs or not. ... The statements present in this block will always execute regardless of whether exception occurs in try block or not such as closing a connection, stream etc.
-
In this video you will learn about the Java exception this fall into two main categories: checked exceptions and unchecked exceptions. In this article, we'll provide some code samples on how to use them.
-
In this video you will learn about the Throw is a keyword which is used to throw an exception explicitly in the program inside a function or inside a block of code. Throws is a keyword used in the method signature used to declare an exception which might get thrown by the function while executing the code
-
In this video you will learn how to create a custom exception in Java. We’ll show how user-defined exceptions are implemented and used for both checked and unchecked exceptions.
-
In this video you will learn about the Threads which allows a program to operate more efficiently by doing multiple things at the same time. Threads can be used to perform complicated tasks in the background without interrupting the main program.
-
In this video you will learn about the Thread class provides the join, method which allows one thread to wait until another thread completes its execution. If t is a Thread object whose thread is currently executing, then t. join, will make sure that t is terminated before the next instruction is executed by the program.
-
In this video you will learn about the Synchronization in java is the capability to control the access of multiple threads to any shared resource. Java Synchronization is better option where we want to allow only one thread to access the shared resource.
-
In this video you will learn about the Inter Thread Communication, if you are aware of inter-process communication then it will be easy for you to understand interthread communication. Interthread communication is important when you develop an application where two or more threads exchange some information.
-
In this video you will learn about the Linked List, it is a part of the Collection framework present in java. util package.

-
In this video you will learn about the Linked List, it is a part of the Collection framework present in java. util package. This class is an implementation of the LinkedList data structure which is a linear data structure where the elements are not stored in contiguous locations and every element is a separate object with a data part and address part.
-
In this video you will learn about the Java Hash Set it class is used to create a collection that uses a hash table for storage. It inherits the Abstract Set class and implements Set interface. The important points about Java HashSet class are: HashSet stores the elements by using a mechanism called hashing. HashSet contains unique elements only.
-
In this video you will learn about the Comparable and comparator, these both are an interface that can be used to sort the elements of the collection. Comparator interface belongs to java.util package while comparable belongs to java. Lang package. Comparator interface sort collection using two objects provided to it, whereas comparable interface compares" this" refers to the one objects provided to it.
-
In this video you will learn about the queue its interface is provided in java. util package and it implements the Collection interface. The queue implements FIFO i.e. First in First Out. This means that the elements entered first are the ones that are deleted first.
-
In this video you will learn about the Map its interface present in java util package represents a mapping between a key and a value. The Map interface is not a subtype of the Collection interface. Therefore, it behaves a bit differently from the rest of the collection types. A map contains unique keys.
-
In this video you will learn about the Map its implementations are grouped into general-purpose, special-purpose, and concurrent implementations.
-
In this video you will learn about JDBC it stands for Java Database Connectivity. JDBC is a Java API to connect and execute the query with the database. It is a part of JavaSE (Java Standard Edition). JDBC API uses JDBC drivers to connect with the database. There are four types of JDBC drivers.

Blockchain is a decentralized, immutable ledger that records transactions across a distributed network of computers. It uses consensus algorithms and cryptographic hashing to ensure trust and security.
Smart contracts are self-executing code stored on a blockchain that automatically enforce rules and execute transactions when predefined conditions are met.
Solidity is a high-level programming language used to write smart contracts on Ethereum. It supports inheritance, libraries, and complex user-defined types.
Gas represents the computational cost of executing operations in Ethereum. Users pay gas fees in ETH to incentivize miners or validators to process transactions.
ERC-20 is a standard for fungible tokens, while ERC-721 defines non-fungible tokens (NFTs), which are unique and indivisible.
Hardhat, Truffle, and Remix IDE are commonly used to write, test, and debug Ethereum smart contracts.
Reentrancy is a security vulnerability where an external contract repeatedly calls back into the calling contract. It can be mitigated using the Checks-Effects-Interactions pattern and reentrancy guards.
DAOs (Decentralized Autonomous Organizations) are community-governed organizations encoded via smart contracts. Members vote on proposals using governance tokens.
Web3.js is a JavaScript library that allows interaction between web applications and Ethereum nodes via JSON-RPC.
IPFS (InterPlanetary File System) is a decentralized storage network used to store and retrieve files in a distributed manner, often for dApps needing off-chain data storage.
