COMP 14: Miscellaneous :) May 30, 2000 Nick Vallidis

Announcements zI made some changes to the P2 assignment (only on hand-in and grading policy) zoutput printout -- It's ok to put the word document on the disk and not print it

Review zWhat is control flow? zWhat are the two types of statements that modify the flow of control?  How does an if statement work? if (condition) statement;

Review (cont.)  How does an if-else statement work?  What if we want to put more than one statement in an if or if-else ? if (condition) statement1; else statement2;

Replacement zWhat do I mean when I type something like ? yI mean that the whole string " " should be replaced by a variable name yExamples from your homework assignment: x" " turns into "Nick Vallidis" x" " turns into "May 30, 2000" zYou'll see other people do this...

Replacement zYou'll also see this done with italics zExamples: ycondition means use a boolean expression ystatement means replace with an actual Java statement

Indenting  Don't forget the way indenting works with if, if-else, and block statements  if : If (x > 255) System.out.println("x is a big 'un."); Indent here!

Indenting  if-else : If (x > 255) System.out.println("x is a big 'un."); else System.out.println("x ain't so big."); Indents here!

Indenting zBlock statements: { System.out.println("x is a big 'un."); System.out.println("x ain't so big."); } Indents here!

Indenting zThis includes class definitions and main! Public class Birthday { public static void main(String[] args) { System.out.println("Hi!"); } Indents here! Two indents here because we're inside 2 block statements

Examples/Exercises zNo homework tonight! (unless of course you'd like to read ahead. I mean you don't have to, but it would probably be a good idea. Sure, everyone deserves a break sometime, but you should be all energized since you just had a long weekend. You should be ready to work your heart out this week. But, hey, it's up to you.)
