Conditional Statements

Simple If Statement

Sometimes you have an action (or several actions) that should be done only under certain conditions.

For example, if a fish is at the wall of an aquarium, it needs to change direction before it can move forward.

    if ( fish.atWall() == true )
    {
        fish.changeDir();
    }

Syntax:

if ( <boolean-expression> )
{
    <the conditional statement(s)>
}
