Java was developed by Sun Microsystems (which is now the subsidiary of Oracle) in the year 1995. James Gosling is known as the father of Java. Before Java, its name was Oak. Since Oak was already a registered company, so James Gosling and his team changed the Oak name to Java.

JAVA PLATFORM

Any hardware or software environment in which a program runs is known as a platform. Since Java has a runtime environment (JRE) and API, it is called a platform.

• Java is a pure object oriented programming language.
• It was developed by ‘James Gosling’ at Sun Microsystems.
• First version of Java was released in 1995.
• Java provides the functionality of ‘write once, run anywhere’ (WORA).

FUNCTION OF JAVA

Java provides a huge library. Auto memory cleanup process i.e. automatic garbage collection. Platform independent means it is portable on every operating system class.

WHY TO LEARN JAVA PROGRAMING?

Java is a MUST for students and working professionals to become a great Software Engineer especially when they are working in Software Development Domain. I will list down some of the key advantages of learning Java Programming:

• OBJECT ORIENTED ? In Java, everything is an Object. Java can be easily extended since it is based on the Object model.

• PLATFORM INDEPENDENT ? unlike many other programming languages including C and C++, when Java is compiled, it is not compiled into platform specific machine, rather into platform independent byte code. This byte code is distributed over the web and interpreted by the Virtual Machine (JVM) on whichever platform it is being run on.

• SIMPLE ? Java is designed to be easy to learn. If you understand the basic concept of OOP Java, it would be easy to master.

• SECURE ? With Java's secure feature it enables to develop virus-free, tamper-free systems. Authentication techniques are based on public-key encryption.

• ARCHITECTURE-NEUTRAL ? Java compiler generates an architecture-neutral object file format, which makes the compiled code executable on many processors, with the presence of Java runtime system.

• PORTABLE ? Being architecture-neutral and having no implementation dependent aspects of the specification makes Java portable. Compiler in Java is written in ANSI C with a clean portability boundary, which is a POSIX subset.

• ROBUST ? Java makes an effort to eliminate error prone situations by emphasizing mainly on compile time error checking and runtime checking.

WHY SHOULD I TAKE CORE JAVA DEVELOPER CRETIFICATION

Learn how to create solutions to real-world problems in the Java Programming Language. This certification covers most essential aspects of Core Java. On the completion of this course, you will have all the basic knowledge that you need to create a functional Java program.

JAVA JOB ROLES

Here are some of the job roles that are available for a professional with Java skills:

• Java Developer
• Java Architect
• Web Developer
• Database Administrator

JAVA CAREER OPPORTUNITIES

Java is currently leading the pack in the enterprise back-end market and the Android mobile application development market. The future looks bright for Java when you consider the integration of modern language features such as lambda expressions and streams in JDK 8. According to Oracle, there are nine million Java developers in the world who continue to work with Java for many reasons such as practicality, compatibility, reliability and ease of use. With plans already afoot to introduce new language features, like value types, in JDK 10, Java might as well emerge as the Programming Language of the Year even ten years down the line!
