Java Program to compare two Byte Arrays
To compare two Byte Arrays, use the Arrays.equals() method. Here we have declared and initialized a total of 4 arrays.
byte[] arr1 = new byte[] { 11, 13, 30, 45, 77, 89 };
byte[] arr2 = new byte[] { 12, 13, 34, 87, 99, 33};
byte[] arr3 = new byte[] { 11, 13, 30, 45, 77, 89 };
byte[] arr4 = new byte[] { 13, 16, 56, 78, 98, 99 };Now, using the Arrays.equals() method, we will be compare two arrays.
Arrays.equals(arr1, arr2);
In the same way, other arrays would be compared one by one.
Let us see the complete example to compare two Byte Arrays.
Example
import java.util.*;
public class Demo {
public static void main(String[] args) {
byte[] arr1 = new byte[] { 11, 13, 30, 45, 77, 89 };
byte[] arr2 = new byte[] { 12, 13, 34, 87, 99, 33};
byte[] arr3 = new byte[] { 11, 13, 30, 45, 77, 89 };
byte[] arr4 = new byte[] { 13, 16, 56, 78, 98, 99 };
System.out.println("Array1 is equal to Array2 = "+Arrays.equals(arr1, arr2));
System.out.println("Array1 is equal to Array3 = "+Arrays.equals(arr1, arr3));
System.out.println("Array1 is equal to Array4 = "+Arrays.equals(arr1, arr4));
System.out.println("Array2 is equal to Array3 = "+Arrays.equals(arr2, arr3));
}
}Output
Array1 is equal to Array2 = false Array1 is equal to Array3 = true Array1 is equal to Array4 = false Array2 is equal to Array3 = false
