A Java Application for Two-Way Chatting

A Java Application for Two-Way Chatting

Posted by | Sep 9, 2008 | |

This Java Code supports two-way chatting between users. It implements a client for the ConnectionBroker server, which can set up a relayed connection between a pair of such clients. There are really two functions: The user can register with the server as a client who is willing to accept a connection, or the user can make a connection with one of the clients who is waiting on the server. The code retrieves and displays a list of waiting clients when it starts. There is a Refresh button that the user can click to refresh this list (since the list of waiting clients can change from time to time).

The Blackjack game written in Java provides a graphical user interface (GUI) for players to enjoy a simplified version of the classic card game. Upon starting the game, players are dealt an initial set of two cards each, and the goal is to build a hand with a total value as close to 21 as possible without exceeding it. The game features a deck of standard playing cards, including numbered cards, face cards (King, Queen, Jack), and Aces, each contributing their respective values to the hand.

Java Code to Demonstrate Recursion

Java Code to Demonstrate Recursion

Posted by | Sep 9, 2008 | |

The Java code implements a simple graphical application that visually represents and counts blobs within a grid by using recursion. A blob is a group of adjacent filled squares in the grid. The application uses Java Swing for creating the graphical user interface (GUI) components. It includes buttons for generating a new set of blobs, counting the number of blobs, and a grid where users can click to get information about the blob size at that specific position. This Java code uses recursion in the getBlobSize method to calculate the size of a blob.

The DynamicArrayOfInt class is a simple implementation of a dynamic array in Java. A dynamic array is a resizable array that can grow or shrink in size as needed. This class provides methods to manipulate and interact with this dynamic array of integers. In the constructor, initially the data array has a size of 1 and grows as necessary.
