What is a Language ?

A Language is a communication media between two persons or two things.

What is Java Language ?

Java language is a programming language and computing platform first released by Sun Microsystems in 1995. Java was originally developed by a Canadian James Gosling at Sun Microsystems (which has since been acquired by Oracle). Java is the underlying technology that powers state-of-the-art programs including utilities, games, and business applications. Java runs on more than 850 million personal computers worldwide, and on billions of devices worldwide, including mobile and TV devices.

Why do I need Java ?

There are lots of applications and web sites that won't work unless you have Java installed, and more are created every day. Java is fast, secure, and reliable. From laptops to datacenters, game consoles to scientific supercomputers, cell phones to the Internet, Java is everywhere!

Java is a general purpose computer programming language that is concurrent, class based, object oriented. It is intended to let application developers "write once, run anywhere" (WORA), meaning that compiled Java code can run on all platforms that support Java without the need for recompilation. Java applications are typically compiled to "bytecode" that can run on any Java virtual machine (JVM) regardless of the underlying computer architecture.

Is Java free to download ?

Yes, Java is free to download. Get the latest version at oracle.com. If you are building an embedded or consumer device and would like to include Java, please contact Oracle for more information on including Java in your device.

What is Java Latest Version ?

The latest version of Java is Java 14. That is Java 14 or Java SE 14 .

When was Java Latest Version Released ?

The Java Latest Version Released on September 15, 2020 . That is Java 15 or Java SE 15 . Java SE 15.0. 1 is the latest release of Java SE Platform. Oracle strongly recommends that all Java SE users upgrade to this release.

Why should I upgrade to the latest Java version ?

The latest Java version contains important enhancements to improve performance, stability and security of the Java applications that run on your machine. Installing this free update will ensure that your Java applications continue to run safely and efficiently. You can learn more about Java Programming Language from Wikipedia.

What is the History of Java Programming Language ?

The java language was initially called Oak after an oak tree that stood outside Gosling's office. Later the project went by the name Green and was finally renamed Java, from Java coffee.

Gosling designed Java with a C/C++ style syntax that system and application programmers would find familiar. Sun Microsystems released the first public implementation as Java 1.0 in 1996. It promised "Write Once, Run Anywhere" (WORA).

Oracle Corporation's acquisition of Sun Micro-systems in 2009-10, Oracle has described itself as the steward of Java technology.

What are the Java Language Principles ?

1. Java must be simple, object oriented, and familiar.
2. Java must be robust and secure.
3. Java must be architecture neutral and portable.
4. Java must execute with high performance.
5. Java must be interpreted, threaded, and dynamic.

How Java Execute Code ?

Java JVM and Java Bytecode

Java is portable, which means that programs written for the Java platform must run similarly on any combination of hardware and operating system with adequate run time support. This is achieved by compiling the Java language code in to an intermediate representation called Java bytecode.

Java bytecode instructions are analogous to machine code, but they are intended to be executed by a Java Virtual Machine (JVM). End users commonly use a Java Runtime Environment (JRE) installed on their own machine for standalone Java applications.

Just-in-time (JIT) compilers that compile byte code to machine code during runtime. Java itself is platform independent and is adapted to the particular platform it is to run on by a Java virtual machine for it, which translates the Java bytecode into the platform's machine language.

Is Java a Compiled or an Interpreted programming language ?

Java implementations typically use a two-step compilation process. Java source code is compiled down to bytecode by the Java compiler. The bytecode is executed by a Java Virtual Machine (JVM).

Modern JVMs use a technique called Just-in-Time (JIT) compilation to compile the bytecode to native instructions understood by hardware CPU on the fly at runtime.
