Not getting any result..

Hi to all , I've started to learn Java a few weeks ago

and my home work was to create a car with license plate and speed as verables.

The speed need to be change by me and can't be more then 100 || less then 0


I've started to wright the program but the answer is always zero..

can any one help me pls..

thanks Guys.


the Code is:

public class Car {

private int Num;
private int Speed;


public Car (int x){
x=Num;
Speed=0;

}

public int SpeedC (){

return Speed;

}
public void SpeedUp (int x){

if (x >= 100)
x=100;
else
x=Speed;

}
public int SpeedUp (){

return Speed+1;

}

public void SpeedDo (int x ){

if (x <= 0)
x=0;
else
x=Speed;

}
public int SpeedDo(){

return Speed-1;

}
public void show(){

System.out.print(Num);
System.out.print(Speed);
}
}

public class Program {

public static void main(String[] args) {

Car car1 = new Car(12345);
car1.show();
Car car2 = new Car(12346);
car1.SpeedUp(5);
car2.SpeedUp(1);
car1.show();
car2.SpeedUp(30);

}
}

Check your methods for adding / decreasing speed.

For the first thing, myint+1 does not add anything to your myint variable. Use myint+=1 (same as myint = myint+1). Also, you allow inifinite modification in the other method, any checking applies only to the the method with param.

Hi Londbrok,
thanks for helping me, I've change the return type as you said ..

but what I don't understand is , why my variable doesn't received in any method ..

Dont know what you mean by that? Show the changes you made, please use [Code] tags

ok Londbrok I've got it ...

what I meant was that when I create new object the method doesn't recognize it
but i found the problem it was incorrect syntax...


Thanks very much Londbrock..
