Book of Programming Ideas
The Book of Programming Ideas document contains 64 example programming exercises for students to try. The sections cover everything from basic input and output exercises through to subroutines, functions, and file handling. There are Python and Java versions of the document, although all exercises are written to be language-independent.
These Java Helpsheets cover various aspects of the language including if statements, data types, loops (while and for), and the Scanner class. Each sheet summarises the concept and provides several example lines of code.
The sheets can be printed out on A4 or A3 paper and make excellent wall displays to help students who are new to programming.
