This is an overview course on Java Programming while the complete detailed-level Java Programming course is available at - https://training.uplatz.com/online-it-course.php?id=java-programming-basics-110.  Java programming is one of the most widely used computer programming languages in today’s time. Be it writing a program for web applications to large systems development, Java programming is used everywhere nowadays. It is a highly reliable, fast and secured programming language and as such, Java has been one of the most favourite programming languages for the developers and other IT professionals.

 

Java programming environment consists of mainly 3 key components namely; (i) Java Development Kit (ii) Java Runtime Environment and (iii) Java Virtual Machine. Java has got a number of advantages which makes it a better choice for the developers. Some of them are (i) Java works on different platforms (ii) It is open-source and free to use (iii) It is a secure programming language along with being a fast and reliable platform (iv) It is Object-Oriented and as such makes it easy for the developers to reuse the code, resulting in lowering the cost.

 

In this Java Programming Course from Uplatz, learners will be able to get an overview of the Java Programming basics, its syntax and types, Classes and Objects in Java, Java Interfaces, Arrays and many more. Learning this course from Uplatz, will help the students in gaining a complete knowledge on the Java Programming Language by which they can upgrade their skills and land up in a high paying job in any organization.

Certification Back to Top

The Java Programming Certification ensures you know planning, production and measurement techniques needed to stand out from the competition. 

Java is a general-purpose programming language that is class-based and object-oriented. The programming language is structured in such a way that developers can write code anywhere and run it anywhere without worrying about the underlying computer architecture. It is also referred to as write once, run anywhere (WORA).

Java is based on C and C++. The first Java compiler was developed by Sun Microsystems and was written in C using some libraries from C++. Java files are converted to bit code format using a compiler that the Java interpreter then executes. Java code runs on Java Virtual Machine (JVM)—the runtime environment.

Java is a well-structured, object-oriented language, which can be considered easy for beginners. You can master it quite rapidly, as there are many processes that run automatically. You don't have to delve into “how the things work in there” too deep. Java is a cross-platform language.

Uplatz online training guarantees the participants to successfully go through the  Java Programming Certification provided by Uplatz. Uplatz provides appropriate teaching and expertise training to equip the participants for implementing the learnt concepts in an organization.

Course Completion Certificate will be awarded by Uplatz upon successful completion of the Java Programming online course.

Career & Jobs Back to Top

The Java Programming draws an average salary of $120,000 per year depending on their knowledge and hands-on experience.

The Java SE 8 Oracle Certified Associate (OCA) certification helps you build a foundational understanding of Java, and gaining this certification credential is the first of two steps in demonstrating you have the high-level skills needed to become a professional Java developer.

The strong community, enterprise support, and growing popularity among programmers show that Java is set to stay the first choice for most businesses. Hence, java career opportunities are not fading anytime soon.

However, most jobs require a set of skills. Specialization is helpful, but technical versatility is also critical. For example, you might get a job to write Java code that connects to a MySQL database.

Note that salaries are generally higher at large companies rather than small ones. Your salary will also differ based on the market you work in.
