Arrays to String Printing with Brackets

Question

I am trying to create a list of random colors using a random generator, which will be used to create a game where the user memorizes the colors. The issue is that my list of colors keeps printing with brackets around it. Any help finding a solution to this is much appreciated!

import java.util.Random;
import javax.swing.JOptionPane;
import java.util.Arrays;

public class Mission13Rivera
{

   public static void main (String[] args)
   {
      //Opening Dialog
      MemoryGame mG = new MemoryGame ();

      Random r = new Random();

      String[] colors = {"red", "white", "yellow", "green", "blue", "orange", "purple", "black", "pink", "gray"};
      String[] solution = new String[6];

      for (int i = 0; i < solution.length; i++)
      {
         solution[i] = colors[r.nextInt(10)];
      }

      JOptionPane.showMessageDialog(null,"The colors are: " + `Arrays.toString(solution));`

   }

}

The result should look like... "The colors are: green, yellow, purple, pink, blue" or whatever other random number combination.

Just started coding, so definitely still learning all of the terms. I appreciate you letting me know, will be learning the differences now. Thanks! — emmiree, Jun 21 '19 at 02:02

The only way to do that would be looping over the solution array and concatenating the values into a string to be displayed in your JOptionPane. The Arrays.toString() methods will not give the output you want.

I don't write much Java, but you're gonna need to loop through the array and construct a string of the values.

String result = "";
for(String color in solution) {
    result += " " + color;
}

A better solution, found here

Arrays.toString(solution).replace("[", "").replace("]", "");
