Keep getting an error message that says code took too long to run

public void charge() { while (!isFullyCharged()); { mBarsCount++; } }

public class GoKart {
  public static final int MAX_ENERGY_BARS = 8;
  private String mColor;
  private int mBarsCount;

  public GoKart(String color) {
    mColor = color;
    mBarsCount = 0;

  public String getColor() {
    return mColor;

  public void charge() {
    while (!isFullyCharged()); {

  public boolean isBatteryEmpty() {
    return mBarsCount == 0;

  public boolean isFullyCharged() {
    return mBarsCount == MAX_ENERGY_BARS;

Woops! You have a semicolon that's run amok! Apparently it's causing an endless loop or something equally dubious.

while (!isFullyCharged()); {  //remove the semicolon between the method call and the curly brace

If you remove that semicolon, your code passes! Happy coding!
