How can I sort an array in Java?

How can I sort an array in Java?

You can use the Arrays.sort() method from the java.util package to sort an array in Java.

Can you show me an example of sorting an integer array?

Sure! Here's a simple example:

import java.util.Arrays;

public class Main {
    public static void main(String[] args) {
        int[] numbers = {5, 3, 8, 1, 2};
        Arrays.sort(numbers);
        System.out.println(Arrays.toString(numbers));
    }
}

This will output: [1, 2, 3, 5, 8]

What if I want to sort an array of strings?

You can use the same Arrays.sort() method. For example:

String[] fruits = {"Banana", "Apple", "Cherry"};
Arrays.sort(fruits);
System.out.println(Arrays.toString(fruits));

This will output: [Apple, Banana, Cherry]

Can I sort in reverse order?

Yes, you can sort in reverse order by using a custom comparator. For example:

Arrays.sort(fruits, Collections.reverseOrder());
