Built-in support for multi-threading, socket communication, and memory management (automatic garbage collection).These classes will help programmers by providing standard methods like reading from the console, writing to the console, saving objects in data structure etc.

Java API (Application Programming Interface) : Set of classes’ written using Java programming language which runs on JVM. Thus for different hardware platforms, one has corresponding the implementation of JVM available as vendor supplied JREs. Like a real computing machine, JVM has an instruction set which manipulates various memory areas at run time. Byte codes are the machine language for the JVM. JVM will become an instance of JRE at runtime of java program.

JVM (Java Virtual Machine): ‘JVM’ is software that can be ported to various hardware platforms.

JRE (Java Runtime Environment): It is part of JDK but can be used independently to run any byte code (compiled java program).

JDK (Java Development Kit): JDK contains JRE along with various development tools like Java libraries, Java source compilers, Java debuggers, bundling and deployment tools Let’s get familiar with various terminologies used by java programmers. Step4 : This byte code can run on any platform or device having JVM (java.exe convert byte code in machine language) Step3 : Byte Code (abc.class) will be generated on disk. Step2 : Compile the abc.java file using “javac” command or eclipse will compile it automatically. Step1 : Create a source document using any editor and save file as. Not only will the program be checked for syntax errors by a Java compiler, but some other libraries of Java code can be added (linked) to your program after the compilation is complete (deployment stage). It gets converted to either machine-specific code or a byte code that is understood by some run-time engine or a java virtual machine. Java requires the source code of your program to be compiled first. String in switch-case, Java nio, exception handling new way For the sake of simplicity, we have not included that additional stuff here. But if you are using any other compiler like Turbo C++, the program needs to be modified to be executed successfully. We have tested this on a Ubuntu Linux system. This program runs fine under GNU Gcc compiler. The Java language is object-oriented (OO), which allows you to easily relate program constructs to objects from the real world. If you master it, your chances of getting employed as a software developer will be higher than if you specialize in some domain-specific programming languages. Java is a general-purpose programming language that’s used in all industries for almost any type of application. Instead, Java runs on a Java Virtual Machine (JVM). Java program can run on a wide variety of computers because it does not execute instructions on a computer directly. In other terms, it is architecturally neutral, which means that you can use Java to write a program that will run on any platform or device (operating system). The goal was to provide a platform-independent alternative to C++. Java was developed by James Gosling from Sun Microsystems in 1995 as an object-oriented language for general-purpose business applications and for interactive, Web-based Internet applications.
