To get a random item from an array in Java, you can use the 'Random' class along with the 'nextInt' method. Here is an example:

import java.util.Random;

public class RandomItemFromArray {
    public static void main(String[] args) {
        String[] array = {'Item 1', 'Item 2', 'Item 3', 'Item 4', 'Item 5'};

        // Create a Random object
        Random random = new Random();

        // Generate a random index within the array length
        int randomIndex = random.nextInt(array.length);

        // Get the random item from the array using the generated index
        String randomItem = array[randomIndex];

        // Print the random item
        System.out.println('Random item: ' + randomItem);
    }
}

In this example, we have an array of strings 'array'. We create a 'Random' object called 'random'. Then, we use the 'nextInt' method of the 'random' object to generate a random index within the range of the array length. Finally, we retrieve the item at the random index from the array and store it in the 'randomItem' variable. The 'randomItem' is then printed to the console.
