Use foreach(for each) style for on a two-dimensional array.

public class MainClass {
  public static void main(String args[]) {
    int sum = 0;
    int nums[][] = new int[3][5];

    for (int i = 0; i < 3; i++)
      for (int j = 0; j < 5; j++)
        nums[i][j] = (i + 1) * (j + 1);

    for (int x[] : nums) {
      for (int y : x) {
        System.out.println("Value is: " + y);
        sum += y;
      }
    }
    System.out.println("Summation: " + sum);
  }
}
