Program Plan Intro

Automobile application

Program plan:

  • In a file “Automobile.java”, create a class “Automobile”,
    • Declare the necessary variables.
    • Define the constructor,
      • Call the method “set_Id()”,
      • Call the method “set_Make()”,
      • Call the method “set_Model()”,
      • Call the method “set_Color()”,
      • Call the method “set_Year()”,
      • Call the method “set_Mpg()”,
    • Define the method “set_Id()”,
      • Initialize the final variable.
      • Check whether either the id is less than “0” or greater than maximum id,
        • If it is true, set the id to “0”.
          • Otherwise, set the initial id.
    • Define the method “set_Make()” to set the initial make value.
    • Define the method “set_Model()” to set the initial model value.
    • Define the method “set_Color()” to set the initial color value.
    • Define the method “set_Year(),
      • Initialize the minimum year and maximum year.
      • Check whether either the year is less than the minimum year or greater than the maximum year,
        • If it is true, set the year to “0”.
          • Otherwise, set the initial year.
    • Define the method “set_Mpg()”,
      • Initialize the minimum and maximum miles per gallon.
      • Check whether either the Miles Per Gallon(MPG) is less than the minimum mpg or greater than the maximum mpg,
        • If it is true, set the MPG to “0”.
          • Otherwise, set the mpg value.
    • Define the method “get_Id()” to return the id.
    • Define the method “get_Make()” to return the Make.
    • Define the method “get_Model()” to return the Model.
    • Define the method “get_Color()” to return the Color.
    • Define the method “get_Year()” to return the year.
    • Define the method “get_Mpg()” to return the MPG.
  • In a file “TestAutomobiles.java”, create a class “TestAutomobiles”,
    • Define the method “main ()”,
      • Call the constructor “Automobile()” that instantiates several job automobile dealers.
      • Call the method “display1()” for first automobile dealer.
      • Call the method “display1()” for second automobile dealer.
      • Call the method “set_Id()” for first automobile dealer.
      • Call the method “display1()” for first automobile dealer.
      • Call the method “set_Id()” for first automobile dealer.
      • Call the method “display1()” for first automobile dealer.
      • Call the method “set_Make()” for first automobile dealer.
      • Call the method “set_Model()” for first automobile dealer.
      • Call the method “display1()” for first automobile dealer.
      • Call the method “set_Id()” for second automobile dealer.
      • Call the method “set_Color()” for second automobile dealer.
      • Call the method “set_Year()” for second automobile dealer.
      • Call the method “display1()” for second automobile dealer.
      • Call the method “set_Mpg()” for second automobile dealer.
      • Call the method “display1()” for second automobile dealer.
      • Call the method “set_Mpg()” for second automobile dealer.
      • Call the method “display1()” for second automobile dealer.
    • Define the method “display1()”,
      • Print the output.

5. Word FrequencyWrite a program that reads the contents of a text file. The program should create a dictio-nary in which the keys are the individual words found in the file and the values are the number of times each word appears. For example, if the word “the” appears 128 times, the dictionary would contain an element with 'the' as the key and 128 as the value. The program should either display the frequency of each word or create a second file containing a list of each word and its frequency.
3.) File Encryption and DecryptionWrite a program that uses a dictionary to assign “codes” to each letter of the alphabet. For example: codes = { ‘A’ : ‘%’, ‘a’ : ‘9’, ‘B’ : ‘@’, ‘b’ : ‘#’, etc . . .}Using this example, the letter A would be assigned the symbol %, the letter a would be assigned the number 9, the letter B would be assigned the symbol @, and so forth. The program should open a specified text file, read its contents, then use the dictionary to write an encrypted version of the file’s contents to a second file. Each character in the second file should contain the code for the corresponding character in the first file. Write a second program that opens an encrypted file and displays its decrypted contents on the screen.
Returns an US standard formatted phone number, in the format of      (xxx) xxx-xxxx           the AreaCode, Prefix and number being each part in order.           Testing Hint: We be exact on the format of the number when      testing this method. Make sure you think about how to convert      33 to 033 or numbers like that when setting your string format. Reminder      the %02d - requires the length to be 2, with 0 padding at the front if a single      digit number is passed in.
