Passing a Reference by String in Java [duplicate]

Question

Is there any way to implement this sort of code in Java?

int foo = 3;
String data = "foo";
System.out.println(StringToReference(data));

and print 3?

Edit: Specifically, I'd like to parse a String or char and return an int representing a KeyEvent. For example, I'd like to be able to do this:

for(char c : "hello")
    new Robot().keyPress(StringToReference("KeyEvent.VK_"+c));

Without knowing exactly what you are trying to accomplish, this is the closest I think you could get:

Map<String, Integer> map = new HashMap<String, Integer>();

map.put("foo", 3);

System.out.println(map.get("foo"));
