Question

Supposes I have some methods like this:

method1()
method2()
method3()
method4()
method5()

But I don’t want to call sequence methods:

obj.method1()
obj.method2()
obj.method3()
obj.method4()
obj.method5()

It’s boring. And if I add a new method: method6(), I need add manual: obj.method6()

It’s better if I can call them using a loop in Java. Anybody can give me some suggestions?

Thank!

Try something like:

   for (int i=0;i<N;i++) {
      try {
        obj.getClass().getMethod("method"+i).invoke(obj);
      } catch (Exception e) {
         // give up
         break;
      }
    }
