  Compare Two Java int Arrays Example
  This java example shows how to compare two integer arrays for equality using
  Arrays.equals method.

    /*
      To compare two int arrays use,
      static boolean equals(int array1[], int array2[]) method of Arrays class.
     
      It returns true if both arrays are equal. Arrays are considered as equal
      if they contain same elements in same order.

    boolean blnResult = Arrays.equals(intArray1,intArray2);
    System.out.println("Are two int arrays equal ? : " + blnResult);
 
    /*
      Please note that two int array references pointing to null are
      considered as equal.
    */
 
  }

/*
Output of the program would be
Are two int arrays equal ? : true
