The selection structure

(Display Listing 1.)

Behavior of the selection structure can be paraphrased as follows:

• If the expression in the conditional clause evaluates to true, execute the statements inside the curly braces following the conditional clause.
• Else (short for otherwise) execute the statements inside the curly braces following the word else.

If the value contained in the variable named testResult is the Boolean value true, the method named say is called on the penguin object to display the word Even.

If the value contained in the variable named testResult is false, the method named say is called on the penguin object to display the word Odd.
