String college=JOptionPane.showInputDialog("Enter college: ");

If you are trying to put that as the name of the college, wherever you declared the name (for ex: collegeName) you would need to do

college = collegeName;
//then declare you name to whatever college you created
methodName  = new Method (collegeName);

//then declare it in your world setup

add(new Location(int x, int y), methodName);

Hope this helps. Took me awhile to figure this out myself :P

It could look like this:

//in world when adding the object to the world
A a = new A();
a.setCollege(college);
addObject(a, x, y);

//in class A
private String college;

public void setCollege(String col)
{
    college = col;
}

If the actor is already in the world, you need to get a reference to it and then call the setCollege method on it. Or you save a reference to it when you create the object and use this reference when you need it.

uhm... how do I get the stored input in the variable college and call the variable in an actor? for example: //in the actor setText("College: " + college); //the college variable is from MyWorld, how do I get that variable and use it in an actor?
