Is there a way in Java to call a method by having its name on a
string?

something as:

void foo(){}
void bar(){}

void callFunction(String s)
{
// Call function s

}

void otherFunction()
{
callFunction("foo");

}

Thanks.

The closest that you are goning to get in introspection -
http://java.sun.com/docs/books/tutorial/javabeans/introspection/index.html

This has pretty much nothing to do with what the OP wants to do.

That document weirds me out, actually. Beans are something i associate
with early java, around 1.1 or something - it's an idea that never
really went anywhere. The fact that support was dropped from NetBeans 6
is telling. And yet someone's gone to the trouble of updating it to use
new-style for loops!

Except that JavaBeans are used all over the place. J2EE containers,
Spring Framework, Hibernate, to name but a few. Even most of the awt and
Swing use JavaBeans.
