Compiler error--but the editor won't show what's wrong.

I'm not able to compile this. For some reason the editor won't even load with error messages. Can anyone see what I'm doing wrong here? Thank you!

GoKart.java 
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 boolean charge() {
    boolean isCharging = true;
    if (!isFullyCharged()) {
      mBarsCount++;
      isCharging = false;
    }
    return isCharging;
    mBarsCount = MAX_ENERGY_BARS;
  }

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

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


}

Your error is on line 22. The return statement on line 21 should happen after you set your variable.

ok, I tried to edit my code a bit, but I'm still getting compiler errors. Am I missing something pretty big here? I may need to be referred to a previous unit. Here's my current code:

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 boolean charge() {
    boolean isCharging = true;
    if (!isFullyCharged()) {
      mBarsCount++;
      isCharging = false;
    }
    return isCharging; 

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

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

}

If you still need help with this, use a while loop in your charge method. like...

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