Method Practice

We learned about methods in grade 11, but not as well as we should have, so here's some review and practice.

Methods Info

• Method names are normally verb-like and are always in lower-camel-case. e.g. isWinner() or drawGraphics() or attackEnemyOnlyAtNight()
• Read over the notes in unit3 from the grade 11 notes
• Have a look at codingbat.com/java if you need more practice writing methods.
• Methods can take zero, one, or many parameters but can only return one thing (or zero).

Practice

Make a class called MethodPractice (or something) and then from public static void main() run (or call) the following methods.

Write methods that do the following:

1. take an int and return its reciprocal as a double
2. take a string and return the length of the string as an int
3. take nothing, return nothing, just print "YOLO"
4. take nothing, return a random number between 1 and 99
5. take a boolean and an int and return a string
6. returns a double with the value of NaN or infinity.

   I'd like to see if I can test if a number is equal to NaN or infinity

Use the output of some of these in your main() method.
