I need more if-statement help

I have this code right now. What I'm trying to do is slowly make the circle bigger until it fully covers the background. What I have so far:

import hsa.Console;
import java.awt.*;
public class GamingProject
{
static Console c;
public static void main (String[] args)
{
c = new Console ();

//Beginning words to set background
Font newFont = new Font("Times New Roman",1,20);
c.setFont(newFont);

c.drawString ("Before the quiz begin, we would just like to ask which one",0,15);
c.drawString ("of these colors is your favorite color?",0,30);

c.setColor (Color.blue);
c.fillOval (50,50,50,50);

c.setColor (Color.red);
c.fillOval (125,50,50,50);

c.setColor (Color.green);
c.fillOval (200,50,50,50);

c.setColor (Color.orange);
c.fillOval (275,50,50,50);

c.setColor (Color.black);
c.fillOval (350,50,50,50);

c.setColor (Color.magenta);
c.fillOval (425,50,50,50);

c.setColor (Color.black);
c.drawString ("My favorite colour is: ",0,155);
c.setCursor (8,24);
String backgroundColor;
backgroundColor = c.readLine();

c.clear();

int y = 150;
int x = 215;

if (backgroundColor.equalsIgnoreCase ("blue"))
{
c.setColor (Color.blue);
c.fillOval (215,150,200,200);

for (y = 150; y <=300; y++)
{
c.setColor (Color.blue);
c.fillOval (215, y,20,20);
for (int counter = 0; counter <2147000000; counter++)
{}

}

(I have more code here but it's unnecessary)

The problem is highlighted in red. It says " "}" is inserted to complete Statement No Short If"

What does that mean?

Are there other ways to make my circle grow bigger?
