Learning Aims - Use loops to repeat tasks

For you to do:

This week we will look at repetition using for loops.

Useful resources to help you out include:

• Otago Level 2 book - Chapter 6. This covers both while and for loops. 6.3 is the for loop part. I'm not covering while loops in the revision in any detail - you can read and try for yourself.

• HTTLACS Chapter 7 - again for loops are covered after while loops https://books.trinket.io/thinkjava/chapter7.html I'd read through - understand and have a go at the repl.it problems. A great explanation of for loops https://funnelgarden.com/java-for-loop/#For_Loop and of course some material from me: https://sites.google.com/netnz.school.nz/csp/l2-revision?authuser=0#h.p_6YFiMm3zEogp

• These are the problems to do:

• 019 https://repl.it/@trevorstorr/2021019-1#Main.java

• 023 https://repl.it/@trevorstorr/202123#Main.java

• 028 https://repl.it/@trevorstorr/2021028#Main.java

• 031 https://repl.it/@trevorstorr/2021031#Main.java

Problem 31 is a bit more difficult.

Note that I am leaving you to explore while loops for yourself - they are quite a bit easier.
