This www page presents a set of Java programming exercises, and sample solutions, for (England, Wales and Northern Ireland) key stages 3 and 4 pupils. Each problem comprises (for download): (i) a .pdf file presenting the problem, (ii) a suite of .java source codes files and (iii) in some cases additional supporting material. All material made available in this collection of www pages is made available free of charge for non-commercial usage. However, except where otherwise indicated, it remains the copyright of the University of Liverpool. Should you choose to make use of any of the material for teaching purposes we would greatly appreciate appropriate acknowledgement.

If you have a particular example problem that you would like to share we would be happy to include this (with appropriate acknowledgement of course).

The problems are categorised as follows:

  1. Sequence: Simple programming problems that use sequences of commands.
  2. Inheritance: Example problems that make use of the inheritance concept which is a feature of object oriented programmimg.
  3. Keyboard Input: Programmig example problem ussng keybopard input (something not quite as straight forward in Java as might be expected).
  4. Selection: Programme example problems that involve selection using "if-else" or "switch" ("case") statements.
  5. Repetition: Programme examples that involve repetition using "for" and "while" loop constructs.
  6. Arrays: Examp;e problems focused on the array daya structure.
  7. File Handling: Example problems that involve file input and outpit (also something that is not quite as straight forward in Java as might be expected).
  8. Landscape Gardening: Example problem exercises directed at a AQA GCSE specimen controlled assessment problem concerned with landscape gardening.

Under eaqch category problems are ordewred according to perceived difficulty.
