This repository includes java projects.

• Assignment-1 includes two small projects.
  • A program that outputs the equation of the perpendicular bisector of the line segment between two points.
  • A small Individual Retirement Scheme program called 'The Private Pension System', PPS.
• Assignment-2
  • A program that allows a car salesman to enter a customer's choices regarding a new car and from that information, itemize the costs of the choices and finally determine the total cost.
• Assignment-3 includes two small projects.
  • A program which takes a sequence of characters and draws the image they represent. The ‘b’s in the sequence are for printing a blank character, ‘s’s for printing ‘*’ and ‘n’s for newline. A digit before any of these characters shows how many times the character should be printed, if the digit is missing, the character should be printed only once.
  • A program to print the letters W, X, Y and Z using the character of ‘*’ with the given size. The user will decide the given size.
• Assignment-4
  • A small String Analyzer Program with a menu. The menu is like:
    Welcome to our String Analyzer Program.
    Please enter your menu choice:
    1. Count number of chars
    2. Print the words in a sentence
    3. Delete substring
    4. Replace substring
    5. Sort characters
    6. Hash code of a string
• Assignment-5 includes two small projects.

  • A program which takes a number (N) from user, and rolls 10 fair six-sided dice, N times. To roll a single dice, you can simply generate a random number between 1 and 6. Use an array to tabulate the number of times each possible total (between 10 and 60) occurs. For example, if the number is 1 for all ten dices, the total of them will be 10. Then print out a text histogram of the results, as illustrated below. A histogram is a graphical representation of a statistical distribution that shows how many elements fall into a set of values.

  • A program which have multiple stages. In the first part, The user needs to take a string from the stdin which shows the content of a 2D array. This string should contain a set of numbers separated by dashes (-), and each number is used for a binary representation of a row. Then, generated binary digits are located to the corresponding row of your 2D array as in the example below. If the user enters a string such as “4-1-7”, then the program should print the following grid:

                                        -------------
                                        | 1 | 0 | 0 |
                                        -------------
                                        | 0 | 0 | 1 |
                                        -------------
                                        | 1 | 1 | 1 |
                                        -------------
    

    After that there are some step operations which is related to the given 2D array such as swapping 2D array's elements based on specific rule.
