Object: Creating Objects

Creating Objects

Point originOne = new Point(23, 94);
Rectangle rectOne = new Rectangle(originOne, 100, 200);
Rectangle rectTwo = new Rectangle(50, 100);

A class provides the blueprint for objects; you create an object from a class.
The new operator requires a single, postfix argument: a call to a constructor.
The new operator returns a reference to the object it created.

This reference is usually assigned to a variable of the appropriate type.

Point originOne = new Point(23, 94);

int height = new Rectangle().height;

The reference returned by the new operator does not have to be assigned to a variable. It can also be used directly in an expression.

Each statement for creating objects has three parts.

Point originOne;
