Obligation:
need to prove termination of the following program:
public class Et1 {
    public static void main(String[] args) {
		Random.args = args;
	    int a = - Random.random(); 
	   	int b = - Random.random();	
	   	while (a > b) {
	   		b = b + a;
 			a = a + 1;
	   	}
    }
}


public class Random {
  static String[] args;
  static int index = 0;

  public static int random() {
      if (index >= args.length)
	  return 0;

      String string = args[index];
      index++;
      return string.length();
  }
}


public class Et2 {
    public static void main(String[] args) {
		Random.args = args;
	    int a =  Random.random(); 
	   	int b =  Random.random();	
	   	while (b > 0) {
	   		int r =  Random.random();		
	   		b = a - 1 - r;
	   	    a = a - 1 - r;
	   	}
    }
}
