Lab Magic Parking Tower

A parking tower is out of order someday. If you park a Benz, you will end up with a Torben. Write a program to simulate this scenario. First create a class called CarParked which has a static method called outOfOrder. Name an object called yourCar, which happens to be a Benz. Your program should contain a class called CarParked and a test program called CarParkedDemo which test the method by CarParked.outOfOrder(yourCar).

1. Do Temperature Project, which is Project 7 (3rd, 2nd ed.) or Project 3 (1st ed.).
Write a Temperature class that has two instance variables: a temperature value(a floating-point number) and a character for the scale, either C for Celsius or F for Fahrenheit. The class should have four constructor methods: one for each instance variable(assume zero degrees if no value is specified and Celsius if no scale is specified), one with two parameter for the two instance variable, and a no-argument constructor (set to zero degrees Celsius). Include the following:

Class Definition 3

Do Display 4.7 (3rd, 2nd ed.) or 4.5 (1st ed.).



Then use Display 4.8 to call 4.7.



In Display 4.7, if the method setDate has the parameter as setDate(int month, int day, int year), what kind of changes should be made in its body of codes?

Average income by gender

Write a program to calculate average income by gender based on the following data, where F stands for female and M for male.
You should be able to allow users to type in a whole line such as F 80,000 followed by next line M 30,100.



F 62,000
M 25,000
F 38,000
F 43,000
M 65,000
M 120,000
F 80,000
M 30,100



Without any change made to your program, your program should be able to process a new set of data, such as follows:

M 52,000
M 35,000
F 48,000
M 33,000
F 75,000
F 110,000
F 90,000
M 30,100

※Project 1 of Chap. 2.
The Babylonian algorithm to compute the square root of a number n is as follows:
1.Make a guess at the answer(you can pick n/2 as your initial guess)
2.Compute r=n/guess
3.Set guess=(guess+r)/2
4.Go back to step 2 for as many iterations asnecessary.The more you repeat step 2
and 3,the closer guess will become to the square root of n.



※Project 3 of Chap. 2.
Write a program that reads in two integers typed on the keyboard and outputs their
sum,difference,and product it.

Homework 3-10-2008: String Processing

Write a program that starts with a line of text and then outputs that line of text with the first occurrence of "hate" changed to "love". For example, a possible sample output might be
The line of text to be changed is:
I hate you.
I have rephrased that line to read:
I love you.



Hint: You may consider use the methods: indexOf(A_String) and substring(Start, End) in your program.
