Store a method's name in a variable and call that method using that variable [duplicate]

Question

I want to call a method whose name (with or without parentheses and parameters) is stored in a string variable and call this method using this variable.

Until now I have found that in Java if you do this:

String str = "func();";
System.out.println(str);

This would call method func(). But I don't think this is recommended. So, my question is:

Is it okay to do this?
Is there any other way to do this?

Thanks.

Your example will simply print out a String that says func();. There's no method name func() being called. It's possible to to achieve that with reflection, but almost always there's a cleaner way to do it. Why do you think you need to invoke methods inside Strings? — Kayaman

That would not call method func(). That would just println func(); — Clark Kent
