Modularization

6 important questions on Modularization

How can you create methods with or without parameters?

To create a method without parameters, simply define the method without any input parameters in the method header. To create a method with parameters, specify the input parameters in the method header and use them within the method body. You can pass values to these parameters when calling the method.

What is the focus of methods that return a value?

Methods that return a value are designed to provide a result or output to the caller. These methods specify a return type in the method header, and the method body performs the necessary computations or operations to generate the desired result. The return statement is used to send the computed value back to the caller.

How can you pass arrays to methods?

Arrays can be passed to methods as arguments by specifying the array name and brackets in the method header. The method can then access and manipulate the elements of the array within its body. Changes made to the array within the method will affect the original array in the calling code.

What is recursion and how is it used in methods?

Recursion: where a method calling itself to solve complex problem elegantly.

Recursion can be used to solve problems that can be broken down into smaller repetitive subproblems.

It often involves a

base case - when the recursion should stop
recursive case - calls the method with a smaller version of the problem.

What are the parts of a method?

The components of a method include the method header (which specifies the modifiers, return type, name, and parameters), the method body (containing the code to be executed), and the return statement (which specifies the value to be returned, if any).

What are some method design issues to consider?

Method design issues include

implementation hiding, which involves encapsulating the internal details of a method
increasing cohesion, which ensures that a method performs a single, well-defined task
reducing coupling, which limits the interdependence between methods and promotes modular programming.
