Announcements

output printout -- It's ok to put the word document on the disk and not print it

Review

What is control flow?What 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

What do I mean when I type something like <variable>? I mean that the whole string "<variable>"

should be replaced by a variable name Examples from your homework assignment:

"<put your name here>" turns into "Nick Vallidis"

"<put date here>" turns into "May 30, 2000"

You'll see other people do this...

Replacement

You'll also see this done with italicsExamples:

condition means use a boolean expression

statement 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

Block statements:{

System.out.println("x is a big 'un.");

System.out.println("x ain't so big.");

}

Indents here!

Indenting

This 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

No 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.)
