When you run a java program from command prompt, you type c:>java name_of_file

Now along with it type 2 and 3. ie
c:>java name_of_file 2 3

This 2 will get stored in args[0] and 3 in args[1] ie in your program where you write
public static void main(String args[])
{
int x= Integer.parseInt(args[0]);
int y= Integer.parseInt(args[1]);
}

Now x =2 and y=3 and you can use it for addition etc.

Hmm.. I know this. This for getting values from the user in command line. This will definitely help me but I was looking for the general method like the one we use in C++

count>> "enter two number";
int num1, num2;
cin<<num1

public static void main(String[]args){
BufferedReader input = new BufferedReader(new InputStreamReader(System.in));

System.out.print("input 1 : ");
int num1 = Integer.parseInt(input.readLine());
System.out.print("input 2 : ");
int num2 = Integer.parseInt(input.readLine());
System.out.println("Result : "+(num1+num2));
//etc...
}
