Program Plan Intro

Reversing a sentence

Program plan:

Filename: “Sentence.java”

This program file is used to define a class “Sentence”. In the code,

  • Define a class “Sentence”.
    • Declare class members “text”.
    • Define a constructor “Sentence()”.
      • Initialize the “text”.
    • Define a method “reverse()”.
      • If the sentence is empty
        • Return.
          • Create the character variable “c” and assign the first element of text to it.
          • Create the object of “Sentence”.
          • Call the method “reverse()”.
          • Add “c” to the result of “rest.getText()”.
    • Define the method “getText()”.
      • Return the “text”.

Filename: “SentenceDemo.java”

This program file is used to define a class “SentenceDemo”. In the code,

  • Define a class “SentenceDemo”.
    • Define a method “main()”.
      • Create the object “greeting” of class “Sentence”.
      • Call the method “reverse()”.
      • Print “text” by calling “getText()”.
      • Print the expected result.

You are given a class that processes purchases for an online store. The class receives calls to: • Retrieve the prices for items from a database • Record the sold items • Update the database • Refresh the webpage a. What architectural pattern is suitable for this scenario? Illustrate your answer by drawing a model for the solution, showing the method calls/events. b. Comment on how applying this pattern will impact the modifiability of the system. c. Draw a sequence diagram for the update operation.
2. The memory management has contiguous memory allocation, dynamic partitions, and paging. Compare the internal fragmentation and external fragmentation for these three approaches. [2 marks] 3. Suppose we have Logical address space = 24 = 16 (m = 4), Page size=2² =4 (n = 2), Physical address space = 26 = 64 (r = 6). Answer the following questions: [4 marks] 1) Total # of pages ? 2) Total # of frames ? 3) Number of bits to represent logical address? 4) Number of bits to represent offset ? 5) Number of bits to represent physical address? 6) Number of bits to represent a page number? 7) Number of bits to represent a frame number / 4. What is translation look-aside buffers (TLBS)? Why we need them to implement the page table? [2 marks] 5. Why we need shared pages for multiple processes? Give one example to show the benefits.
