Compare two int arrays in a single line in Java

Two int arrays can be compared in Java using the java.util.Arrays.equals() method. This method returns true if the arrays are equal and false otherwise. The two arrays are equal if they contain the same number of elements in the same order.

A program that compares two int arrays using the Arrays.equals() method is given as follows −

Example

 Live Demo

import java.util.Arrays;
public class Demo {
   public static void main(String[] argv) throws Exception {
      boolean flag = Arrays.equals(new int[] { 45, 12, 90 }, new int[] { 45, 12, 90 });
      System.out.println("The two int arrays are equal? " + flag);
   }
}

Output

The two int arrays are equal? true

Now let us understand the above program.

The Arrays.equals() method is used to compare two int arrays. If they are equal then true is stored in flag and if they are not equal then false is stored in flag. The value of flag is displayed. A code snippet which demonstrates this is as follows −

boolean flag = Arrays.equals(new int[] { 45, 12, 90 }, new int[] { 45, 12, 90 });
System.out.println("The two int arrays are equal? " + flag);
