In this section, we will learn what is a method in Java, types of methods, method declaration, and how to call a method in Java. What is a method in Java?

2024年2月29日 · Methods are essential for organizing Java projects, encouraging code reuse, and improving overall code structure. In this article, we will look at what Java methods are and how they work, including their syntax, types, and examples.

To call a method in Java, write the method name followed by a set of parentheses (), followed by a semicolon (;). A class must have a matching filename (Main and Main.java). Like we specified in the Classes chapter, it is a good practice to create an …
