Question 1.
What does a nested loop do in Java?
Show hintHide hint
Think about how many loops you see.
Question 2.
How many lines will the outer loop iterate if it runs from 1 to 5?
Show hintHide hint
Count the numbers from 1 to 5.
3Question 3.
How many times will the outer loop run in the example triangle printing program?
- 3
- 5
- 7
Show hintHide hint
Count how many iterations the outer loop is set.

- Neither
Show hintHide hint
Which loop affects the other?
Question 5.
Create a program that uses nested loops to print a series of increasing and decreasing triangles. How would you implement this?
Show hintHide hint
Consider different conditions for the outer loop.
Question 6.
Modify the triangle printing example to also print each line number preceding the stars. How would that affect your nested loop?
Show hintHide hint
What additional output do you need to include inside the outer loop?
