Changing the elements in an array using [index]

1 

import org.code.neighborhood.Painter;

public class MyNeighborhood {
  public static void main(String[] args) {

String[] paintColors = new String[3];
    
    String[] paintColors = {"Red", "White", "Blue"};
   ArrayPainter myArrayPainter = new ArrayPainter(5, 0, "south", 18, paintColors);
    myArrayPainter.moveAndPaint();

  }
}
In the ArrayPainter subclass:
public class ArrayPainter extends Painter {

  private String[] paintColors;

  public ArrayPainter(int x, int y, String direction, int paint, String[] paintColors) {
    super(x, y, direction, paint);
    this.paintColors = paintColors;
  }
  public String[] getPaintColors() {
    return paintColors;
  }

  public void moveAndPaint() {
   int index = 0;
    while(index < paintColors.length) {
      move();
      paint(paintColors[index]);
      index++;
    }
    
  }
  public void setColor(int index, String newColor) {
  return paintColors[index] = newColor;
    
  }
  
}

When I try to run my code, the error is within this line:
public void setColor(int index, String newColor) {
return paintColors[index] = newColor;

The goal of this method is to change one or more colors in the array.

Please post your actual code instead of a picture.

Changed it. Thanks for letting me know; it’s my first day on here.

can you be more explicit and show us the text of the error?

also please confirm the language of this code? (looks like java to me)

your function declares a void return but then tries to return a value?
this may cause an error.

also noticed that you are declaring paintColors twice (the first one says it is a string array and the second one creates an array of three string literals)
