ObjUse-WE5-P1

Section 3.11 ObjUse-WE5-P1

Classify method as static method or instance method
1. If static, use the class name
2. If instance, must have or create an instance
Write (instance / class) dot method name and ( )
Determine whether parameter(s) are appropriate
1. Number of parameters passed must match method declaration
2. Data types of parameters passed must match method declaration (or be assignable)
Determine what the method will return (if anything: data type, void, print, change state of object) and where it will be stored (nowhere, somewhere)
Evaluate right hand side of assignment (if there is one). Value is dependent on method’s purpose
