here your JVM is created

How to Download and install JDK and create JVM (Java Virtual Machine) and run your first java program

Follow the Following steps

Now we have successful JVM (Java Vertual Machine) have created to test it see as Step5

Step 5.

open "Command Prompt" and Type "java -version" and heat the enter button then you can see your version of JDK

Step 6.
 Now to run your first java program follow these steps
1.create a java program such as

public class Hello
{
public static void main(String []args)
{
System.out.println("hello world");
}
}

2. save it as Hello.java it necessary to save your program file as similar to your class name of program as in my case i save it on my desktop such as "Hello.java"
