APCSA Unit 5 Review

What is a condition that should be true when a method is called?

Cannot have any return type, even void.

A variable declared in a method is local to that method and cannot be used outside of it.

Most objects contain accessor and mutator methods to allow the client to manage data in a controlled manner.

A return value must match the return type in the method header.

When a method is called, the formal parameters are copied into the actual parameters. The types of the corresponding parameters must match.

You can have multiple methods with the same name in the same program.

A method invoked through one object may take as a parameter another oject of the same class.

Instance variables should be declared with public visibility to protect their data.

Each object has a state and a set of behaviors.
