Compare Two Java int Arrays Example


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

import java.util.Arrays;

public class CompareIntArraysExample {

 
public static void main(String[] args) {
   
//create int arrays
   
int[] intArray1 = new int[]{27,78,1023};
   
int[] intArray2 = new int[]{27,78,1023};
   
   
/*
      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
