MIS 260 Practice - week 3

 

  1. Visit the class web page, and then download DebugTwo1, DebugTwo2, and DebugTwo3 Java files. Each of the files has syntax and/or logical errors. In each case, determine the problem and fix the program.
  2. Write a Java program that declares variables to represent the length and width of a room in feet. Use Room as the class name. Assign appropriate values to the variables—for example, length = 15 and width = 25. Compute and display the floor space of the room in square feet (length * width). Display more than just a value as out put; also display explanatory text with the value. Save the program as Room.java 

                        Output:     The floor space is 375.0 square feet.              

  1. Write a Java program that declares variables to represent the length and width of a room in feet, and the price of carpeting per square foot in dollars and cents. Use Carpet as the class name. Assign appropriate values to variables. Compute and display, with explanatory text, the cost of carpeting the room ((length * width)*price).  Save the program as Carpet.java This program's output should look similar to following: The floor space is 375 square feet.      

                        Output:     The floor space is 375.0 square feet.     
                                        The Price for carpet is $1968.75       

  1. Write a Java program that declares variables that represents hours and minutes worked on a job. Assign appropriate values to variables. Use Time as a class name. This program should display the value in hours and minutes. Use 197 minutes for this program. 197 minutes becomes 3 hours and 17 minutes.  Save the program as Time.Java

                        Output:     197 mutes becomes 3 hours and 17 minutes   
                                       

  1. Write a program that calculates and displays the amount of money you would have if you invested $1,000 at 5 % (equivalent to 0.05) interest for one year. Use the formula:           Future Amount = principal + principal * Rate* Time    Save the program as Interest.java

                Output:     The amount for $1000.0 invested for 1 year  at 0.05 is : 1050.0
                                          

Java Assignment 2: (Turn in by email – attach the program)

Due: will be announced by instructor

Score: 10 points

 

  1. Write a program to convert Fahrenheit temperature to Centigrade. You MUST use Two variables. One for representing Fahrenheit and the other for representing Centigrade. Otherwise, you will lose points. Use the normal human body temperature of 98.6 degrees Fahrenheit, as the test case. Use the formula: Centigrade = (Fahrenheit – 32)*(5.0/9.0). Save the program as FahrenheitToCentigrade.java

                        Output:     Centigrade equivalent: 37.0
