Can someone provide a definition for iteration?
Wiki says.
Iteration means the act of repeating a process with the aim of approaching a desired goal, target or result.
Each repetition of the process is also called an "iteration," and the results of one iteration are used as the starting point for the next iteration.
Iteration is used to repeat sections of code.
Why might iteration be useful in a program using arrays?

6. Recording new knowledge
Know that iteration (repetition) is used to repeat sections of code.
Understand why iteration is a key construct in programming.
Be able to define and demonstrate a For loop.
In a new blog post :
Can you provide a definition for iteration.
In your own words give reasons why iteration is a useful programming skill.
Ask for a peer assessment of your work – can you improve this ‘revision’ quality definition?
Can you compare your understanding with the information presented on the Java Docs For loop page.

Finding out facts
Know that iteration (repetition) is used to repeat sections of code.
Understand why iteration is a key construct in programming.
Be able to define and demonstrate a For loop.
Now develop your blog post further including information on For loops in Java.
Can you provide a definition?
Can you give examples of how you could/have used for loops in your code?
How many alternative ways can you demonstrate?

Blog Post Update
Know that iteration (repetition) is used to repeat sections of code and why.
Understand why iteration is a key construct in programming.
Be able to define and demonstrate a For loop.
Assess your blog post definition on Count Controlled For Loops.
Have you mentioned:
Count-Controlled
Repeats a fixed number of times based on:
Limit
Increment
Good for arrays or when number of repetitions is known in advance.
