How to define an updated variable in java?

Question

Hello,
What i am trying to do is to have a variable that keeps its value updated when the program execuation finishes For example
public class class1
private static int x =0;
main()
x++;
Run 1 ..... x = 1;
run 2.........x =2;
run 3........x =3
I know that you can do that in VB using static variable? Is there the same thing in java? if there is not , then how can i know how many times my program runs?
Thanks

ThanksCreate a class with static int x that extends Serializable, call it SaveX. Make setX and getX static methods for SaveX.
When executing your program deserialized SaveX. If the deserialization process gets an FileNotFoundException or IOException then instantiate the SaveX. That is your initial execution.
Increment x. For example:
int myX = SaveX.getX();
myX++;
SaveX.setX(myX);Serialize the class.
Each time the program is executed x will be incremented and saved. The first execution start x at zero and saves the first serialized class.
