Modify the drive method to define a parameter of how many laps should be driven. Update the method body to handle the ne

So, we need to locate the method and see how it currently operates.

 public void drive() {
    lapsDriven++;
    barCount--;
  }

The drive method currently takes no parameters. (Parameters are bits of information to be used in the method.) In this case, we need to add a parameter by declaring its type and giving it a name. We will also adjust our increment/decrement shorthand to use the input param to increment/decrement our variaables. see the code below.

 public void drive(int laps) { //<-- note the added parameter in the method parentheses
    lapsDriven+= laps; // note we no longer use the double ++ or --, but use the += and -= and the passed in parameter
    barCount-= laps;
  }

class GoKart { public static final int MAX_BARS = 8; private String color; private int barCount; private int lapsDriven;

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

public String getColor() { return color; } public void charge() { barCount = MAX_BARS; }

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

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

public void drive() { lapsDriven++; barCount--; }

public void drive(int laps) { //<-- note the added parameter in the method parentheses lapsDriven+= laps; // note we no longer use the double ++ or --, but use the += and -= and the passed in parameter barCount-= laps; } }

I was intending to help you try to solve the problem. Is there some specific question you need answered, or concept that is hard to grasp that you would like explained?
