Summary

Overview: 4.6.0

In chapter 4 we learned about loops
- loops are used to repeat a statement/block

Body of a Loop
- The statement or block which follows a loop and is to be repeated. If the body contains multiple statements, it must be enclosed by curly brackets
For Loop
- A loop that has a header with 3 optional parts: initialization, condition, and change.
- Initialization happens once before the loop ececutes
- Checks the condition before every iteration
- Executes the change at the end of every loop
Infinite Loop
- A loop that never ends.
Loop
- A way to repeat one or more statements in a program.
Nested Loop
- One loop inside of another.
Out of Bounds error
- A run-time error that occurs when you try to access past the end of a string or list.
Trace Code
- Writing down the values of the variables and how they change each time the body of the loop executes.
While Loop
- A loop that repeats while a Boolean expression is true.

while
- Begins a while loop
for
- starts a for/for each loop
System.out.println(variable)
- Prints the value of a variable
- Useful for tracing code execution and debugging

Forgetting to change the thing you are testing in a while loop
- Infinite loop!
Getting the start and end conditions wrong for a for loop
- Results in an out of bounds error
Jumping out of a loop too early using a return statement
