I am trying to print 5 random colors (colors can be repeated as long as they are random) from an array of 10 colors that I created. I know I'm close-ish, but I'm not sure where I'm going wrong.

import java.util.Random;

public class RandomColors

 public static void main (String args)
 
 Random r = new Random();

 String colors = "red","green","blue","yellow","brown","black","white","indigo","orange","purple";
 String solution = new String[5];

 for(int i = 0; i < solution.length; i++)
 
 solution[i] = colors[r.nextInt(10)];
 System.out.println(i);
 

 

I know my problem is that I'm trying to print "i", but I'm not sure what I should be combining to print.

Just Replace

System.out.println(i);

with

System.out.println(solution[i]);

You have a problem that your algorithm might return the same color several times (r.nextInt(10) can return the same value multiple times).

A more straightforward solution could be to convert the array to a list, shuffle it (this is the "random" part), and print the first 5 elements:

List<String> colorsList = Arrays.asList(colors);
Collections.shuffle(colorsList);
colorsList.stream().limit(5).forEach(System.out::println);

Since the question was edited to say that non-unique colors are allowed, they can be printed like this:

IntStream.generate(() -> r.nextInt(colors.length))
 .limit(5)
 .mapToObj(i -> colors[i])
 .forEach(System.out::println);

This generates a stream of 5 random integers, and prints the elements by accessing the array.

Simply print solution[i] instead of i:

System.out.println(solution[i]);
