Comparing the contents of two different multi dimensional arrays

Question:

How can you compare the contents of two different multi dimensional arrays?

Answer:

Use Arrays.deepEquals(array1, array2)

Code:

import java.util.Arrays;
 
class CompareArrays {
   public static void main (String[] args) {
 
      int[][] array1 = { {1,2}, {1,2}, {1,2} ,{1,2}, {1,2} };
      int[][] array2 = { {1,2}, {1,2}, {1,2} ,{1,2}, {1,2} };
      int[][] array3 = { {1,2}, {1,2}, {1,2} ,{1,2}, {1,3} };
 
      if (Arrays.deepEquals(array1, array2)){
         System.out.println("array1 and array2: same content");
      } else {
         System.out.println("array1 and array2: different content");
      }
 
      if (Arrays.deepEquals(array1, array3)){
         System.out.println("array1 and array3: same content");
      } else {
         System.out.println("array1 and array3: different content");
      }
 
   }
}

Output:

$ java CompareArrays
array1 and array2: same content
array1 and array3: different content
