Java Coding Samples   Various Java programs to illustrate various concepts    A   Hello World!   Java program.    Calling Methods .  A sample of how to call methods in the same class.    For loop .  A simple example of using for loops to calculate factorial. Uses the built in int data type so only good to 13!    Enhanced for loop      Value Parameters :  An example that shows the behavior of value parameters. In Java all parameters are passed by value.    String Example .  A few brief examples of String manipulations.    BinaryConverter  .  A program with examples of various Java syntax that converts a  base 10 int to base 2 String.    PrimeEx A program with various approaches to determine if an int is prime or not. Used to demonstrate Java syntax. You need the   Stopwatch   class, a non standard Java class, as well.    Pointers as Value parameters      Array Examples      2D array Example .  A simplified version of filtering a picture represented by ints.    2D array example .  Very simple version of the Conway's Game of Life.    Getting input from Keyboard with Scanner class      Reading ints from file with Scanner class      Writing ints to file      Connecting to and reading from a web page.      Program to create ASCII frequency table from file and url.   Demonstration of try / catch blocks. The CIA 2008 Factbook may be downloaded from  Project Gutenberg .      IntListVer1   First version of the IntList class developed in class. Developing class to illustrate various class design and implementation issues in Java.    IntListTesterVer1      IntListVer2   Added default add method, equals method, and toString methods. Includes versions of toString using String concatenation and StringBuffer to illustarte  performance differences.    IntListTesterVer2      IntListVer3 .  Added insert and remove methods.    SortedIntList .  Inherits from InListVer3 to create a SortedIntList. Class is "broken"  because random insertions still allowed.    GenericList .  Altered the list to store anything, not just ints.    Die   class. A class that models a playing die.    DemoClass :  This illustrates some of the more confusing concepts in class syntax and mechanics such as constructors, static vs. instance methods, and method overloading.    Stopwatch class .  A class for measuring how long it takes for a program to run. o   Documentation for Stopwatch class.      Create a Set .  A method that using polymorphism to create a set from an array.    Recursion examples .  Includes examples on finding space taken up by files in a directory including all files in all subdirectories, recursive factorial, recursive power, recursive Fibonacci numbers, and a simple knapsack problem.    Eight Queens example .  Code to find a a solution to an N queens problem. Note the queensAreSafe method has not been completed.    Airlines example .  Determine if airlines can be moved from airline to another based on network of airline partners. Here is a   sample input file .      Minesweeper  .  Another example of recursion from the game minesweeper.    GenericListVersion2 .  Changed the GenericList class so that it implements the   Iterable   interface in order to demonstrate how to implement an   iterator    using an inner class.    GenericListVersion3 .  Changed GenericList so it is generic based on Java generics syntax instead of relying on Object.    ListNode .  A singly linked node class used to build linked lists    IList .  A simple list interface    LinkedList .  Similar to the LinkedList developed in class. Does not contain all the methods you would expect of a LinkedList. Also implements the iterator remove method in O(N) time. An O(1) time remove method is possible.    UnsortedHashSet -  An unsorted set that uses a hashtable with closed address hashing to store values. Currently only the add method is implemented.    UnsortedSetTest   - A method to compare Java's TreeSet and HashSet to the BianrySearchTree, UnsortedSet, and UnsortedHashSet classes developed in class.  Note you need a lot of other files for this to work.    SimpleWordCount -  Program demonstrating use of a map to count the frequency of words in a file.    WordCount -  Program that compares counting words in files using an ArrayList and a Map.
