  • Pick a bicycle brand and create a new class of bicycles for that brand, as described in the sectionsWhat is an interface?andWhat is a Class?
  • For the new method implementation, write in the console "Clang! Clang!..." for how many times the parameter indicates.
  • Create another class, with a main method, in which you will take a trip aroound your house, changing your bicycle attributes, starting and ending from a complete stop, and ringing the bell once at start and twice at the end. Use as inspiration the method in
  • Your trip must have at least 5 different parts in which you change your bicycle state and print its state (starting and ending from a rest state).
  • Make sure the program runs, screenshot the output without showing the username/ or change the username to reemghousheh
Program 2:name it: **A mountain bicycle**

Instructions:

  • continue the previous program:" a bicycle"
  • Asubclasss of you bicycle class for a mountain bicycle, as described in the section:Classes
  • Your brand comes with a water bottle (both the generic and mountain type). Add a new field that will keep the percentage of water remaining in the bottle (1 full, 0 emptty, 0.5 half empty), as described in the section:Declaring member variables.The water bottle is emptty by default.
  • Declare a method to completely fill the water bottle. Declare a method to completely drink the water. No parameters needed. See:Defining methods.
  • Declare a method that will specify how much to fill the water bottle, as a percentage. If the bottle has already that quantity, do nothing. The method must have the same name as above. A parameter is needed.
  • Declare a method that will specify how much to drink from the water as a percentage. The method must have the same name as above. A parameter is needed.
  • Create a new constructor that will specify the initial cadence, gear and water level. See:Providing Constructors for Your Classes

Program 5: Name it: **Deck of Cards**
Requirements:Start creating a program that will play Poker with the computer,

Instructions:

  • Create an enum type for the suits keeping a name, a short name, color and a rank (clubs, c, black, 4), (diamonds, d, red, 3), (hearts, h, red, 2) and (spades, s, black, 1). Use a boolean for color.

  • Create a card class that will keep the suit and value of the card. It is an immutable class, not allowing its values to change.
    • Two fields, one for suit and one for value of the above enum types. They must be private and final.
    • One constructor specifying the suit and value
    • Getters for each field
