Java Java Objects (Retired) Harnessing the Power of Objects Methods and Constants

Help me with this challenge!

Question: These GoKarts have a single rechargeable battery that have a display of bars to measure its energy level. Each battery has a maximum of 8 bars.

For this task, let's add a constant field to the class that stores the maximum number of energy bars. Make sure the field cannot be changed and is accessible from the class, not just the instance. Use the naming convention we learned.

public class GoKart { public static final int MAX_B = 8; public final int mBattery; private String mColor;

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

public String getColor() { return mColor; }

public void battery() { mBattery = MAX_B; }

}

GoKart.java
public class GoKart {
  public static final int MAX_B = 8;
public final int mBattery;
  private String mColor;

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

  public String getColor() {
    return mColor;
  } 

  public void battery() {
    mBattery = MAX_B;
  }

}

This code worked for me:

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

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

public void load() { mBarsCount = MAX_BARS; }

public String getColor() { return mColor; } }

What issues are you getting with your code?

One thing that I've noticed. Should mBattery be declared as final? Try it without the final keyword - see if that helps.

Change

private int mBattery;

and add inside the constructor mBattery = 0;

then should work

TRY THIS

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

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

public String getColor() { return mColor; } }

public class GoKart { public static final int MAX_BARS = 8; public final int Battery; private String Color;

public GoKart(String color) { this.Color = color; }

public String getColor() { return Color; }

public void battery() { this.Battery = MAX_BARS; }

}
