LAB 9:

[1] Define a class named Rectangle. A Rectangle object stores an (x, y) coordinate of its top/left corner (0, 0), a width, and a height. (5 pts)

Each Rectangle object should have the following public methods:

Rectangle(x, y, width, height) Constructs a new rectangle whose top-left corner is specified by the given coordinates and with the given width and height.

getX() Returns this rectangle's leftmost x-coordinate.

getY() Returns this rectangle's top y-coordinate.

getWidth() Returns this rectangle's width.

getHeight() Returns this rectangle's height.

toString() Returns a String representation of this rectangle, such as "Rectangle[x=1,y=2,width=3,height=4]".

contains(x, y) Returns whether the given Point's (x, y) coordinates lie inside the bounds of this rectangle.

equals(rect)

Returns whether the given other rectangle rect is a rectangle with the same x/y coordinates, width, and height as this rectangle.

getArea() Returns an area of this rectangle. (Ref. area = width * height)

moves(dx, dy) Moves the rectangle by dx and dy.

Test your program by running it with the TestRectangle class.

[2] Please write a BankAccount class, which maintains a pair of account information (name, balance) of all the customers. You also need to build the main class such as BankAccountMain, which contains main() method and sequence of statements for: (1) reading account information from file; (2) constructing an array of BankAccountobjects; and (3) calculating and printing the average balance, minimum, and maximum balance among the whole accounts. (5 pts)

The program is expected to read all the account information from account.txt, and assign the first integer number of the first line to the number of accounts variable (like a numAccount) and proceed to capture the accounts information from the successive name (String) and balance (double) pair in the file. Accounts information of the individual customers is kept in the array of BankAccount object.
