Compare Two Java long Arrays
To compare two Java long arrays in Java, use Arrays.equals() method. Let’s say we have the following long arrays.
long[] arr1 = new long[] { 767, 568, 555, 897, 678 }; long[] arr2 = new long[] { 456, 756, 555, 999, 678}; long[] arr3 = new long[] { 767, 568, 555, 897, 678 };
Now, we can compare the equality of these arrays using the equals() method.
Arrays.equals(arr1, arr2); Arrays.equals(arr2, arr3); Arrays.equals(arr1, arr3);
The following is the complete example.
Example
import java.util.*; public class Demo { public static void main(String []args) { long[] arr1 = new long[] { 767, 568, 555, 897, 678 }; long[] arr2 = new long[] { 456, 756, 555, 999, 678}; long[] arr3 = new long[] { 767, 568, 555, 897, 678 }; // comparing System.out.println(Arrays.equals(arr1, arr2)); System.out.println(Arrays.equals(arr2, arr3)); System.out.println(Arrays.equals(arr1, arr3)); } }
Output
false false true
