Java programing problem

A simple (mono threaded) Java Program will run until it has no more statements to execute or until it encounters a return statement in the main method.

Make sure, when your condition is false, to either a) just return, or b) to have your actual code in an if or else block.

a)

public static void main(String[] args){
    if(someCheck){
        return;
    }
    // actual code here
}

b)

public static void main(String[] args){
    if(someCheck){
        // actual code in here
    }
    // program ends here
}

You can terminate the Java Virtual Machine like that:

System.exit(0);

See the documentation http://download.oracle.com/javase/1,5.0/docs/api/java/lang/System.html#exit(int)

Here you can also find a short explanation how a Scanner works.

if (condition) {
   System.exit(0)
}

This will make your program exit when condition is true. exit is a static method on java.lang.System You can return other values than 0 to signal the status of the exit as appropriate.

As many have already pointed out System.exit(0) is the way to terminate your application. So you have two arrays.

Pseudo code

loop thru array1
 if(array1[i] != condition)
  System.exit(0)
loop thru array2
 if(array2[i] != condition)
  System.exit(0)

You should be more specific about the condition question you have, it's not very clear now.
