I have prblem with instance variables in java ..

How can I find three instance variables that they have different type and each one have tow method?

(Your class should have constructor that initializes the three instance variables)) what does it mean ??

I wait you >>

Hello,
I think this is what you are looking for

public class Example{
  int temp;
  Example(){
    temp++;
  }
  public static void main(String[] args){
    Example e = new Example();
    System.out.println("No. of instances  for e  : " + e.temp);

    Example e2 = new Example();
    System.out.println("No. of instances  for e  : " + e.temp);
    System.out.println("No. of instances  for e2  : " + e2.temp);

    Example e3 = new Example();
    System.out.println("No. of instances  for e  : " + e.temp);
    System.out.println("No. of instances  for e2  : " + e2.temp);
    System.out.println("No. of instances  for e3  : " + e3.temp);

      }
}
