where am i coding wrong?

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

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

public String getColor() { return mColor; }

public void charge() { mBarsCount = MAX_BARS; } public boolean isBatteryEmpty(){ return mBarsCount == 0; } public boolean isFullyCharged(){ return mBarsCount = true;

}

}

GoKart.java
public class GoKart {
  public static final int MAX_BARS = 8;
  private String mColor;
  private int mBarsCount;

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

  public String getColor() {
    return mColor;
  }

  public void charge() {
    mBarsCount = MAX_BARS;
  }
  public boolean isBatteryEmpty(){
    return mBarsCount == 0;
  }
  public boolean isFullyCharged(){
    return mBarsCount = true;

  }

}

mBarsCount is an int variable. What you're writing in your code is "set mBarsCount to be true, and pass it back to the isFullyCharged method". You can't set an int to be true.

Look at your isFullyCharged method.
