Question

I want to read a function’s name from the console, and then calling it in that class.
So, instead of checking which function it is using the “IF” statement, I wish it to happen automatically.

Exmp.  
_ (CONSOLE)  
BuildDatabase (WRITTEN IN CONSOLE)  
---> What happens in class : Class.BuildDataBase(); 

Can it be done?
Another question – how can I run my class’ main from a command line?

Thanks ahead

Answer 1

You can use reflection for that:

Method method = YourClass.getMethod(nameReadFromConsole); //no parameters
method.invoke(null); // invoking without a target object - i.e. static

Running from console is done via the java command – java ClassName
