What is Java? | What Java means and its types?

Java is a high-level programming language or we can say Java is a general-purpose, class-based, object-oriented programming language developed by Sun Microsystems in 1995. Java programs are interpreted by JVM(Java Virtual Machine).It is a computing platform for software development.java runs on multiple platforms.Java is platform independent ,This means all Java programs  can run on different platforms, including Windows,Macintosh, and Unix computers.

Java is fast, secure, and reliable, That's why. It is broadly used for developing Java applications in laptops, data centers,  scientific supercomputers,  etc.

What is Java Platform?

Java Platform is a collection of software products that help programmers to develop and run Java programming applications efficiently. It includes an execution engine(Called as JVM ,that allows Java programs to do the same thing on different computer systems.), a compiler, and a set of libraries in it. It is a set of computer software and specifications. James Gosling developed the Java platform at Sun Microsystems, and the Oracle Corporation later acquired it.

This capability of being able to develop software on one platform and running it on other platforms is called "cross-platform capability".

why do I need it?

There are lots of applications and websites that will not work unless you have Java installed, and more are created every day. To run that kind of applications in system we need java.

What is the full form of Java?

Java does not have any full form, but  The developers of Java were drinking coffee while they were deciding the name of their programming language. So, they gave it the name "Java" as a slang of "Coffee"

Java written in which language?

The very first Java compiler was developed by Sun Microsystems and was written in C using some libraries from C++. Today, the Java compiler is written in Java, while the JRE is written in C.03-Aug-2009

Goals of JAVA | Principle of Java

• It must be simple, object-oriented, and familiar.
• It must be robust and secure.
• It must be architecture-neutral and portable.
• It must execute with high performance.
• It must be interpreted, threaded, and dynamic.
