Selecting Random Elements from an Array

To randomly select a name from a predefined collection, begin by establishing an array containing potential name options.

// Define an array of sample names
String[] nameList = {"Alice", "Bob", "Charlie", "David", "Emily"};

Next, utilize Java's built-in Random class to generate a random index within the bounds of the array length.

import java.util.Random;

// Initialize random number generator
Random generator = new Random();

// Generate random index based on array size
int randomIndex = generator.nextInt(nameList.length);

// Retrieve name at the generated position
String selectedName = nameList[randomIndex];

Finally, display the chosen name through standard output.

// Print the randomly selected name
System.out.println("Selected name: " + selectedName);

import java.util.Random;

public class NameSelector {
    public static void main(String[] args) {
        // Available name options
        String[] candidates = {"Alice", "Bob", "Charlie", "David", "Emily"};
        
        // Setup random selection mechanism
        Random rng = new Random();
        
        // Determine random position
        int position = rng.nextInt(candidates.length);
        
        // Extract chosen element
        String result = candidates[position];
        
        // Display outcome
        System.out.println("Chosen name: " + result);
    }
