How to Sort a String Array in Dictionary Order in Java - Step by Step Examples

How to Sort a String Array in Dictionary Order in Java ?

Answer

To sort a string array in Java in dictionary order, you can use the `Arrays.sort()` method. To sort in descending order, you can use a custom comparator or reverse the array after sorting.

✐ Examples

1 Sort String Array Ascending

In this example,

We create a string array `words` with unsorted elements.
We use the `Arrays.sort()` method to sort the array in ascending dictionary order.
We print the sorted array using a for loop.

Java Program

import java.util.Arrays;

public class Main {
    public static void main(String[] args) {
        String[] words = {"banana", "apple", "orange", "grape"};
        Arrays.sort(words);
        System.out.print("Sorted Array Ascending: ");
        for (String word : words) {
            System.out.print(word + " ");
        }
    }
}

Output

Sorted Array Ascending: apple banana grape orange

2 Sort String Array Descending

In this example,

We create a string array `words` with unsorted elements.
We use a custom comparator to sort the array in descending dictionary order.
We print the sorted array using a for loop.

Java Program

import java.util.Arrays;
import java.util.Comparator;

public class Main {
    public static void main(String[] args) {
        String[] words = {"banana", "apple", "orange", "grape"};
        Arrays.sort(words, Comparator.reverseOrder());
        System.out.print("Sorted Array Descending: ");
        for (String word : words) {
            System.out.print(word + " ");
        }
    }
}

Output

Sorted Array Descending: orange grape banana apple
