Final answer:
A method's inputs are parameters and its output is the return value.
Step-by-step explanation:
A method's inputs are typically defined using parameters, which are the values that are passed into the method when it is called. Parameters allow the method to perform operations or calculations using specific values. On the other hand, a method's output is represented by its return value, which is the value that the method returns after it has finished executing.
For example, let's say we have a method called calculateSum that takes two parameters: num1 and num2. The method calculates the sum of the two numbers and returns the result. In this case, num1 and num2 are the inputs of the method (parameters), and the sum is the output (return value).
