What is java programming?
JAVA is a programming language that creates programs that operate inside a virtual machine. It is used to create programs for mobile devices like android and iPhone. Javac compiler is the tool to compile a java program to byte code. The byte code is sent to the JVM. Java- the virtual machine is an environment where java programs operate.
Java training in Coimbatore will help students to understand object-oriented programming in a better way. They will get an understanding of how to write a program using Java. The course also includes a session on how to debug programs written in Java.
This is an abstract machine that can be thought of as a computer. Its working is completely different from a normal computer. For instance, if we think of numbers as characters, then JVM is a computer where the characters like 0, 1, 2, etc., are stored in the memory. It allows the execution of java programs.
You can access those numbers from java programs. In the JVM environment, java programs run like an operating system is present. To use this java operating system. You will need a java program called JRE. This java program is a collection of programs that provide a common interface to other software. JRE is called a JRE

What are the different types of JVM?
1.J2ME
J2ME is one of the most basic types of JVM. The java compiler is responsible for it. J2ME is used to create programs for mobile devices. The j2me is only present on certain mobile devices like Blackberry.
2.J2SE
This is the most basic type of JVM, which is used to develop java programs. The j2se is an evolution of J2ME. J2SE is used to develop programs for desktop devices. Its supported by the following desktop machines: 1. Windows 2. Mac 3. Unix 4. Linux.
3.J2EE
This is the most complex type of JVM, which is used to develop java programs for the internet. J2EE is an evolution of J2SE. It is supported by the following internet browsers: 1. Internet Explorer 2. Netscape 3. Mozilla 4. Opera 5. Konqueror 6. Web Browsers 7. Android
4.J2K
J2K is one of the most commonly used types of JVM. It is used to develop programs for the internet. It is not supported by the internet browser. You can use J2K to develop programs for the internet.
5. JVM
This is one of the most widely used types of JVM. It is used to develop java programs that are run in the JVM environment. Java can also be called a programming language. It is a multi-platform environment that supports the following platform: 1. Windows 2. Linux 3. Unix 4. Mac OS X 5. Android 6. Google Chrome.
