Dear Nikhil ,

I would recommend to go back and watch previous videos , to strengthen knowledge about those concepts since they are the fundamental building blocks for Java language.

1st : static and void (are only method and class keywords , as far as I'm concerned) so they can be omitted.

2nd : The variable should have '()' since it's not a method / constructor / function

3rd : That leaves us with : 

private int barCount;

and one thing to note : you're missing a class constructor to set initial values for the properties of your object

so the complete code should look like this : 

public class GoKart { 

// Class field declaration 
private static final int MAX_BARS = 8;
private String color;
private int barCount

// Constructor for the class
public GoKart(String color) {
this.color = color;
barCount = 0;
}

// Declare the charge method 
public void charge() {
barCount = MAX_BARS
}

}

So this is how the final answer should look like I encourage you to practice more till you get the hang of things , I know Java can be a very verbose language , but it has it's own pro's and cons as well as a steep learning curve and I wish you the best of luck. for further question you can message me at twitter @itz_pauz
