Answers

1.	- boolean
2.	- alters the flow of program execution based on the evaluation of a boolean expression
3.	- iteration statements repeat the statements located in their body based on the results of an expression
4.	- int, char, byte, short
5.	- a do/while statement will execute its body code at least once
6.	- when you need to execute the statements contained in the iteration statement body at least once
7.	- when your evaluation criteria is based on an int, short, byte, or char
8.	- to prevent case statement fall-through
9.	- it exits the inner-most enclosing iteration statement
10.	- it will exit the named iteration statement
11.	- it will stop execution and start at the beginning of its enclosing iteration statement
12.	- it will stop execution and begin execution of the named iteration statement
