Arrays.compare(char[], char[]): This method is available in java.util.Arrays class of Java.

Syntax:

int java.util.Arrays.compare(char[] a, char[] b)

This method takes two arguments of type char array as its parameters. This method compares two char arrays lexicographically.

Parameters: Two parameters are required for this method.

a: the first array to compare.

b: the second array to compare.

Returns:

1. The value 0 if the first and second arrays are equal and contain the same elements in the same order.

2. A value less than 0 if the first array is lexicographically less than the second array.

3. A value greater than 0 if the first array is lexicographically greater than the second array.

Approach

Java

import java.util.Arrays;

public class Arrayscomparechar {
    public static void main(String[] args) {

        // for char type
        char charArraya[] = { 'a', 'd', 'f',
                                   'h', 'o' };
        char charArrayb[] = { 'a', 'd', 'f',
                                   'h', 'o' };

        System.out.println(Arrays.compare(charArraya, 
                              charArrayb));
    }
}

Output:
