            System.out.print("\t"+subject+"\t"+score [i][0]+"\t"+score [i][1]+"\t"+avrg);
            
      }
}

error = java.lang.ArrayIndexOutOfBoundsException: Index 2 out of bounds for length 2 at array2.main

How do I fix this?

total = score [i][0] + score [i][1];

This line expect to get "i" but loop already closed.

To fix - close for loop after printing this line:

System.out.print("\t"+subject+"\t"+score [i][0]+"\t"+score [i][1]+"\t"+avrg);
