Sample text

Com ACROSS 3. A variable that can contain the address of an object. 6. The region of a program to which an identifier’s declaration applies. 7. The separation of a program into components that are coherent units. 8. A new, that is, non-primitive type. 9. In a class, a method whose name is the same as the class’s name and whose purpose is to initialize a calling object’s fields. DOWN 1. The ability of a class to have methods with the same method identifier but different parameter lists. 2. A method’s identifier together with the number and types of parameters in order.

If the developer of the original class replaces the incorrect or inefficient code, our class would still be erroneous or inefficient. 3. 3 Inheritance We should write program components that are reusable. For example, instead of defining a method that calculates the average gross pay of 10 employees, we would achieve wider applicability by defining a method that calculates the average gross pay of any number of employees. By writing reusable code, we not only save time, but we also avoid the risk of incorrectly modifying the existing code.

For example, here is the interface for figures: public interface Figure { final static int MAX_X_COORD = 1024; final static int MAX_Y_COORD = 768; /** * Draws this Figure object centered at the given coordinates. * * @param x – the X coordinate of the center point of where this Figure * object will be drawn. * @param y – the Y coordinate of the center point of where this Figure * object will be drawn. * */ void draw(int x, int y); /** * Moves this Figure object to a position whose center coordinates are * specified.
