Write Methods

Let’s give your Java code some structure and reusability. In this lesson, you’ll learn how to write your methods—reusable blocks of logic.

Goal

You’ll aim to:

• Write and call methods.

• Understand void vs. return methods.

• Clean up your main method.

Define a method

To define a method, you need to specify:

1. Access modifier (e.g., public, private): Determines the method’s visibility.

2. Return type (e.g., void, int, String): Defines what the method will return, if anything.

3. Method name: The name used to call the method.

4. Parameters (optional): Variables that allow you to pass information into the method.

5. Body: The block of code that gets executed when the method is called.
