Method Call using method name as string

Hi All,
Say i have a class A with 10 methods in a class.
and one of the methods being
public void doWork(){
System.out.println("test"};
}
i have another class B in which i have created an object of the A class .
now in the main method of class B i take an argument "doWork" which is a string (obvioulsy)
is it possible for me to call the methods on the class A based on the string variable which is going to be exactly the name of the method .??
how do i do this ..
hey i dont want to use any if or any other conditional blocks ..
something like
//String s = "doWork"
//s"();"
Thanks Guys ..
Sunil
