A few project examples:

• Write a Java program that performs a 'search and replace' on a given piece of text.
• Write an applet that can be used to calculate mortgage payments.
• Implement a Graph class that will store vertices and edges read from a file, then determine the shortest path between two vertices.
• Create a Java Swing application that draws basic shapes in various sizes and colors while playing a background music clip.
• I need a priority queue that can store objects of any class that implements the Comparable interface. Demonstrate its functions with a console-based driver program.
