Key Concepts

Method Signature

A method signature defines the method's name, its return type, and its parameters. It is critical to ensure that the signature accurately reflects the intended operation so that the method can be correctly invoked and integrated with other parts of the program.

Parameter Passing

Parameter passing refers to how arguments are sent to a method. In this context, using pass-by-value ensures that the original arguments cannot be altered inside the method, which meets the requirement for unchangeable inputs.

Immutability

Immutability in the context of method parameters means that the inputs passed to the method cannot be modified. By using pass-by-value rather than pass-by-reference (ref keyword), the method protects the original values from any alterations during execution.

Data Types

Understanding data types is essential because the method is designed to receive integer inputs, but it must return a fractional result. This requires proper conversion between integer data types for the grades and a double data type to accurately represent the computed average.

Return Type

The return type of a method indicates the type of value that the method produces after execution. In this scenario, the method must return a value with a fractional component, necessitating the use of a double return type to accommodate precision.
