2)My First Java program using Command Prompt:

Step 1: Create your java program in notepad and save the file with extention *.java 
/* This is a My First Java program.*/ class MyFirstProg { // Your program begins with a call to main(). public static void main(String args[]) { System.out.println("This is My First Java Program"); } }

Step 2: Need to set java path
If your *.java file is saved outside the JDK/bin folder you need to set java path.
There are 2 ways i.e Temporary and permanent 

How to set temporary path:
1)Go to command prompt and go to the location where the *.java file is placed.

2)Find the JDK/bin path and execute that in command prompt
set path= C:\Program Files\Java\jdk1.6.0_35\bin

How to set permanent path:
Go to MyComputer properties -> advanced System settings -> environment variables -> new tab of user variable -> write ‘path’ in variable name -> write path of bin folder in variable value -> ok -> ok -> ok

Step 3:Compile the *.java file using the command ‘javac file_name.java’ in command prompt
              Here *.class file will be created in the folder where you are in 

Step 4: Execute the *.java file using the command ‘java file_name’
