Declaration
Following is the declaration for java.util.Arrays.equals() method
public static boolean equals(int[] a, int[] a2)
Parameters
a − This is the array to be tested for equality.
a2 − This is the other array to be tested for equality.
Return Value

Exception
NA
Example
The following example shows the usage of java.util.Arrays.equals() method.
Live Demopackage com.tutorialspoint; import java.util.Arrays; public class ArrayDemo { public static void main(String[] args) { // initializing three integer arrays int[] arr1 = new int[] { 10, 12, 5, 6 }; int[] arr2 = new int[] { 10, 12, 5, 6 }; int[] arr3 = new int[] { 10, 5, 6, 12 }; // comparing arr1 and arr2 boolean retval = Arrays.equals(arr1, arr2); System.out.println("arr1 and arr2 equal: " + retval); // comparing arr2 and arr3 boolean retval2 = Arrays.equals(arr2, arr3); System.out.println("arr2 and arr3 equal: " + retval2); } }
Let us compile and run the above program, this will produce the following result −
arr1 and arr2 equal: true arr2 and arr3 equal: false
