How to Sort a List of Strings in Dictionary Order in Java ?

Answer

To sort a list of strings in Java in dictionary order, you can use the `Collections.sort` method.

✐ Examples

1 Sort List of Strings Using Collections.sort

In this example,

We import the necessary classes for using java.util.Collections and java.util.List.
We create a list named words1 with some strings.
We use the Collections.sort method to sort the list in dictionary order.
Finally, we print the sorted list to standard output.

Java Program

import java.util.Collections;
import java.util.List;
import java.util.ArrayList;

public class Main {
    public static void main(String[] args) {
        List<String> words1 = new ArrayList<>();
        words1.add("banana");
        words1.add("apple");
        words1.add("grape");
        words1.add("orange");
        Collections.sort(words1);
        System.out.println("Sorted list 1 in dictionary order: " + words1);
    }
}

Output

Sorted list 1 in dictionary order: [apple, banana, grape, orange]

2 Sort Another List of Strings Using Collections.sort

In this example,

We create another list named words2 with different strings.
We use the Collections.sort method to sort this list in dictionary order.
Finally, we print the sorted list to standard output.

Java Program

import java.util.Collections;
import java.util.List;
import java.util.ArrayList;

public class Main {
    public static void main(String[] args) {
        List<String> words2 = new ArrayList<>();
        words2.add("pear");
        words2.add("kiwi");
        words2.add("lemon");
        words2.add("apple");
        Collections.sort(words2);
        System.out.println("Sorted list 2 in dictionary order: " + words2);
    }
}

Output

Sorted list 2 in dictionary order: [apple, kiwi, lemon, pear]
