The loops in your code should be used only for iterating the one dimensional array but you are passing two dimensional array. Therefore error occurs. Here is a code that satisfies your requirement.

public class test {

      public static void show(int x[][],int y[][]){
        for(int i=0 ; i < x.length ; i++){    
           for(int j=0 ; j < x[i].length ; j++){
            System.out.print(x[i][j]+" ");
         }
         System.out.print("  ");
           for(int j=0 ; j < y[i].length ; j++){
            System.out.print(y[i][j]+" ");
        }
        System.out.println();
        }
      }
      public static void main(String a[]) {
            show(new int[][] { {1,2,3}, {4,5,6},{7,8,9}},new int[][] { {11,12,13}, {14,15,16},{17,18,19}} );

            }
            }
