Java Programming Abstract Classes and Methods Outcomes: Student will demonstrate the ability to create abstract classes. Student will demonstrate the ability to create abstract methods. Student will demonstrate the ability to to use both concrete and abstract methods in an abstract class. Student will demonstrate the ability to use abstract methods to impose rules on all child classes. Program Specifications: Make up your own theme for this assignment. (Explain it briefly in your submission comments.) Make up your own classes for this assignment. Create an Abstract Class with Abstract Methods, a class that uses the abstract methods and a test class. Create all necessary setters, getters, constructors and methods. Create a reasonable test case Create UMLs for all non-test case classes. Submission Requirements: Follow the rules from the prior assignments. YOU MAY NOT EVER: Use global variables. Use the word goto. Use the break command outside a case statement.

Consider a byte-addressable computer with 16mb of main memory, a cache capable of storing a total of 64kb of data and block size of 32 bytes. (a) how many bits in the memory address? (b) how many blocks are in the cache? (c) specify the format of the memory address, including names and sizes, when the cache is: 1. direct-mapped 2. 4-way set associative 3. fully associative

Write a program that displays the following menu: geometry calculator 1. calculate the area of a circle 2. calculate the area of a rectangle 3. calculate the area of a triangle 4. quit enter your choice (1-4): if the user enters 1, the program should ask for the radius of the circle and then display its area. use the following formula: area = ď€(the square of r) use 3.14159 for ď€ and the radius of the circle for r. if the user enters 2, the program should ask for the length and width of the rectangle and then display the rectangle’s area. use the following formula: area = length * width if the user enters 3, the program should ask for the length of the triangle’s base and its height, and then display its area. use the following formula: area = base * height * .5 if the user enters 4, the program should end. input validation: display an error message if the user enters a number outside the range of 1 through 4 when selecting an item from the menu. do not accept negative values for the circle’s radius, the rectangle’s length or width, or the triangle’s base or height. note: if the user enters an improper menu choice (1-4), the program prints "the valid choices are 1 through 4. run the program again and select one of those." if the user enters a negative radius, the program prints "the radius can not be less than zero." if the user enters a negative value for height or base, the program prints "only enter positive values for base and height."
