2.5 Calling a Non-void Method

Enduring Understanding

Some objects or concepts are so frequently represented that programmers can draw upon existing code that has already been tested, enabling them to write solutions more quickly and with a greater degree of confidence.

Learning Objective

Call non-static non-void methods with or without parameters.

Essential Knowledge

Non-void methods return a value that is the same type as the return type in the signature. To use the return value when calling a non-void method, it must be stored in a variable or used as part of an expression.
