Random Nickname Generator

The following Java code generates nick names based on three arrays which contain adjectives and subjects. The key points learning from making this generator was the following:

• Making an array in Java.
• Generating random numbers withint a certain range (length of an array) to index the arrays.
• concatenate the words chosen from each array to make the full nickname.

import java.util.ArrayList;
import java.util.Random;

public class RandomNameGenerator {
    public static void main(String[] args) {
        System.out.println(randomName());
    }

    public static String randomName() {
        // Create lists
        ArrayList<String> list1 = new ArrayList<>();
        list1.add("Adorable");
        list1.add("Beautiful");
        list1.add("Cute");

        ArrayList<String> list2 = new ArrayList<>();
        list2.add("little");
        list2.add("tiny");
        list2.add("gorgeous");

        ArrayList<String> list3 = new ArrayList<>();
        list3.add("baby");
        list3.add("puppy");
        list3.add("bear");

        // Create an instance of Random
        Random random = new Random();

        // Generate random indices and construct the name
        String answer;
        int randomInt1 = random.nextInt(3);
        answer = list1.get(randomInt1) + ' ';
        
        int randomInt2 = random.nextInt(3);
        answer += list2.get(randomInt2);
        answer += ' ';
        
        int randomInt3 = random.nextInt(3);
        answer += list3.get(randomInt3);

        return answer;
    }
}

Static Functions (side note)

• non-static methods can only be called by class objects not the class itself.
• static variables in a class cannot be reset/redefined through objects of that class (e.i. catCount)
