What does a repeated algorithm step become in Java?
Short answer. A loop, usually while or for.
Why comment the step numbers?
So the code can be matched to the algorithm, which earns marks.
Step to code
| Step says | Java |
|---|---|
| Read n | nextInt() |
| If ... | if |
| Repeat | while loop |
| println |
Remember
| One step, a few lines of code |
| Comment the step number |
You have the algorithm. How does it become Java? Translate one step at a time. Read becomes nextInt. If becomes if. Repeat becomes a loop. Print becomes println. Each step becomes a few lines. Comment the step number.
