How to check if Two Lists are Equal in Java ?

Answer

To check if two lists are equal in Java, you can use the equals method or the Arrays.equals method.

✐ Examples

1 Check Equality Using equals Method

In this example,

We create two lists: list1 and list2 with initial values.
We use the equals method to check if list1 equals list2.
Finally, we print the result to standard output.

Java Program

import java.util.Arrays;
import java.util.List;

public class Main {
    public static void main(String[] args) {
        List<Integer> list1 = Arrays.asList(1, 2, 3);
        List<Integer> list2 = Arrays.asList(1, 2, 3);
        boolean result = list1.equals(list2);
        System.out.println("Are the lists equal? " + result);
    }
}

Output

Are the lists equal? true

2 Check Equality Using Arrays.equals Method

In this example,

We create two arrays: array1 and array2 with initial values.
We use the Arrays.equals method to check if array1 equals array2.
Finally, we print the result to standard output.

Java Program

import java.util.Arrays;

public class Main {
    public static void main(String[] args) {
        int[] array1 = {1, 2, 3};
        int[] array2 = {1, 2, 3};
        boolean result = Arrays.equals(array1, array2);
        System.out.println("Are the arrays equal? " + result);
    }
}

Output

Are the arrays equal? true
