Practice Problems

I am trying to get ready for my Beginning Java Final and am looking for SIMPLE problems where I can practice Java syntax (e.g. for class, method, objects, etc.). Unfortunately, the two books that I have only provide problems that require 100s of lines of code (usually, with 3 lines that exercise the technique they are trying to teach).

Can anyone suggest a place where I can go to get simple problems to exercise the referenced items?

Your assistance is appreciated.

Here is a list of free on-line Java tutorials and books that I have found useful. Many of them contain practice exercises of various sizes.

Sun's Java Tutorial

Introduction to Computer Science using Java by Bradley Kjell

Introduction to Programming Using Java by David J. Eck

Dick Baldwin's Java Programming Tutorials

Interactive Programming In Java by Lynn Andrea Stein

Bruce Eckel's Thinking In Java

JavaRanch's own Campfire Stories

Allen B. Downey's How To Think Like A Computer Scientist

Contest samples

Here's a contest I was in last year... got third place...

Here's a few more I can remember:

1. Take 2 input string which are numbers in base 13 (1-B), and multiply them together, printing the result in base 13. (no using converstion methods of Integer)

2. Take an input number n, and consider an n x n grid. How many different ways are there to go from the bottom left corner to the top right corner, if the only legal moves are up and left?

3. Take an input n, and print out an n-row pascal's triangle. Make sure it's spaced nice and pretty.

If I think of anymore, I'll post them.
