How can I write a helper method using Boolean function?

public void boolean isFullyCharged() { mBarsCount = MAX_BARS; }

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

  public void boolean isFullyCharged() {
  mBarsCount = MAX_BARS;
  }
  public String getColor() {
    return mColor;
  }

  public void charge() {
    mBarsCount = MAX_BARS;
  }
}

1 Do not use void, use just boolean 2 Do not use assignment operator =, use equality operator == 3 Use return statement

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

When the return type is boolean, we should not use void to it as you have in your function:

public void boolean isFullyCharged() {
  mBarsCount = MAX_BARS;
  }

Change your boolean function to this:

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

Hope it helps!

Happy coding!
