Topic 1.9: Method Signatures

• LO 1.9.A: Identify the correct method to call based on documentation and method signatures.
  • EK 1.9.A.1: A method is a named block of code. Procedural abstraction allows use without knowing the implementation.
  • EK 1.9.A.2: A parameter is a variable in the method header. The method signature is the name and parameter list.
• LO 1.9.B: Describe how to call methods.
  • EK 1.9.B.1: A void method has no return value.
  • EK 1.9.B.2: A non-void method returns a value.
  • EK 1.9.B.3: An argument is the value passed to a method. Java uses call by value.
  • EK 1.9.B.4: Methods are overloaded when there are multiple methods with the same name but different signatures.
