Java: Methods & Classes

What you will learn

Class structure, method signatures, and the static keyword.

A class is a blueprint. A method is a named block of code inside a class.

public class Greeter {
    public static String greet(String name) {
        return "Hello, " + name + "!";
    }

    public static void main(String[] args) {
        System.out.println(greet("Alice"));
    }
}

Method anatomy

• access modifier: public, private, protected
• static: belongs to the class, not instances
• return type: void means returns nothing
• parameters: in parentheses
• body: in { }
