Accessing private class methods

Question

This program works, but I am having some problem grasping the concept. If class Room can access methods in class House using gethWidth() and getHeight(), why is it that class Type cannot access those same
methods. Instead, it can only access setWidth() and
setHeight()?
class House {
private double width;//width of room
private double length;//length of the room
double getWidth() {return width;}
double getLength() {return length;}
void setWidth(double w) {width=w;}
void setLength(double l) {length=l;}
void showdim() {
System.out.println("My townhouse has two bedrooms.");
class Room extends House {
String bedroom;
double area() {
return getWidth() * getLength();
void showBedroom() {
System.out.println("The biggest room is the" + " " + bedroom + ".");
class Type {
public static void main(String args[]) {
Room r1=new Room();
Room r2=new Room();
r1.setWidth(14.5);
r1.setLength(20.6);
r1.bedroom="master bedroom";
r2.setWidth(15.2);
r2.setLength(15.3);
r2.bedroom="Guest Room";
System.out.println();
r1.showdim();
r1.showBedroom();
System.out.println();
System.out.println("The area of the" + " " + r1.bedroom+ " " +
"equals"+ " "+ r1.area()+ " " + "square feet.");
}

Thanks to all. But the comments provided so far does not answer my question. Over the past few days I have struggled over the question and I think I found the answer. Others are welcome to comment.
Initially, "width" and "length" were decleared as private in class "House". For other classes to gain access, they had to use "accessor methods". Two accessor methods were decleared: "getWidth" and "getHeight"; and "setWidth" and "setLength". The first two methods "return"; the last two were "void". In class Room, I set up a method to return the calculation, so I used "getWidth and "getLength". In class "Type" I had to use the other method "setWidth", since I was declearing the actual values. Makes sense?
