Question

What I’m trying to do is calling methods/objects with string variables.

I’ve got ‘foo‘ and ‘bar‘ and need to do foo.bar()

Is there something like PHP’s call_user_func()? Any other suggestions?

In java you should use reflection.

official documentation: http://docs.oracle.com/javase/tutorial/reflect/index.html

your case could look like this:

Class<?> c = Class.forName("foo");
Method  method = c.getDeclaredMethod ("bar", new Class [0] );
method.invoke (objectToInvokeOn, new Object[0]);

where objectToInvokeOn is the instance/object (of class foo) you want to call on. In case you have it.

Otherwise you should go for:

Class<?> c = Class.forName("foo");
Object objectToInvokeOn = c.newInstance();
Method  method = c.getDeclaredMethod ("bar", new Class [0] );
method.invoke (objectToInvokeOn, new Object[0]);
