When you evaluate door == "t" it is not checking to see if door has that value. It is checking to see if the bits are the same. In the case of a String object, that means "are they pointing at the same place in memory?", not "are they equal in value?" Because the bits are the location where the object's data is stored. With an integer you are dealing with a primitive so the bits are a value and not a memory location. As GeeTwo said, if you use if(door.equals("t")) you will get the comparison you want.
