Tester

public class Tester {
     public static void main(String[] args) { 
       
      final int ROWS = 2;
      final int COLUMNS = 2 + 2;

      for(int i=0; i < ROWS; i++)
          System.out.print(i);

      System.out.println();

      for(int j=0; j < COLUMNS; j++)
          System.out.print(j);
      
   }
}

What is the output?
