Flow of Control

Default Flow of Control (p. 44)

Method Call and Return (Ch. 2.3.7)

(perhaps we will look at trace of CyberPet example from Ch. 2.3.8, using BlueJ's debugger)

if statement (Ch. 3.6.1)

syntax: 
if ( boolean expression )
       statement;
or with compound statement: 
if ( boolean expression ) {
       compound statement
}
Note that the compound statement can itself include a (nested) if statement

if-else statement (Ch. 3.6.2)

syntax: 
if ( boolean expression )
       statement1;
else 
       statement2;

pitfall: the dangling else (Ch. 3.6.4)

How would the following be interpretted: 

if (condition1)
    if (condition2)
        System.out.println("One");
else
    System.out.println("Two");

switch statement
