如何使用java按升序生成数字的顺序？

Question

I want to create a java method to generate sequential numbers in ascending order. Which I can use to generate automatic TestStep IDs for my TestNG automation. I just want to call this method and the numberings should happen sequentially for each teststep

Answer 1

The question is a bit unclear. I'm assuming you want to count the number of tests and this number is going to be their ID. You could have some static and non-static variables and use static one as a counter. Something like this:

class Test {
    private static int ID_POOL = 0;
    public final int uniqueID;
    
    public Test() {
       uniqueID = ID_POOL++; // generate ID
    }
}

Alternatively:

  private static int ID_POOL = 0;
    
  int generateID() {
    return ID_POOL++;
  }
