Creating an arrays of objects from a class

Question

I was wondering does any one know how to create an array of objects from a class?
I am trying to create an array of objects of a class.
class name ---> Class objectArray[100] = new Class;
I cant seem to make a single class but i need to figure out how to create an array of objects.
I can make a normal class with Class object = new Class

There are four lines of code in your for-loop that actually do something:
for(index = 0; index < rooms.length; index++) {
/*1*/  assignWidth.setWidth(Double.parseDouble(in.readLine()));
/*2*/  rooms[index] = assignWidth;
/*3*/  assignLength.setWidth(Double.parseDouble(in.readLine());
/*4*/  rooms[index] = assignLength;
}1.) Sets the width of an object, that has been instantiated outside the loop.
2.) assigns that object to the current position in the array
3.) Sets the width of a second object that has been instantiated outside the loop
4.) assigns that other object to the current position in the array
btw.: I bet you meant "assignLength.setLength(Double.parseDouble(in.readLine());" in line 3 ;)
Since each position in an array can only hold one value, the first assignment (line 2) is overwritten by the second assignment (line 4)
When I said "construct a new room-object and assign it to rooms[index]" I meant something like this:
for(index = 0; index < rooms.length; index++) {
    Room aNewRoom = new Room();
    aNewRoom.setWidth(Double.parseDouble(in.readLine()));
    aNewRoom.setLength(Double.parseDouble(in.readLine());
    rooms[index] = aNewRoom;
}1.) Constructs a new Object in every iteration of the for-loop. (btw: I don't know what kind of objects you're using, so this needs most likely modification!!)
2.) set the width of the newly created object
3.) set the length of the newly created object
4.) assign the newly created object to the current position in the array

btw. this would do the same:
for(index = 0; index < rooms.length; index++) {
    rooms[index] = new Room();
    rooms[index].setWidth(Double.parseDouble(in.readLine()));
    rooms[index].setLength(Double.parseDouble(in.readLine());
}but be sure you understand it. Your teacher most likely wants you to explain it ;)
