In Java, a method is a collection of statements that perform a specific task. You can think of methods as functions that belong to an object. Defining a method allows you to reuse code, making your program more modular and easier to maintain. Below are the key components of a Java method.

public returnType methodName(parameters) {
    // Code to be executed
}

Here’s a simple example of a method that takes two integers and returns their sum. The return type indicates the type of value the method will return, and the parameters are the values you pass to the method.

public int add(int a, int b) {
    return a + b;
}

You can call a method by using its name along with the necessary arguments. For example, if you want to add two numbers using the add method defined earlier, you can do it as follows:

int result = add(5, 3);
System.out.println("The sum is: " + result);

Methods can also have no return value, in which case the return type is declared as void. Here's an example of a method that prints a message without returning anything:

public void printMessage(String message) {
    System.out.println(message);
}

Incorporating methods into your Java program not only makes your code cleaner but also facilitates debugging and testing. By breaking your code into smaller, manageable methods, you can isolate and fix issues more efficiently.

public class Main {
    public static void main(String[] args) {
        int sum = add(10, 20);
        System.out.println("Result: " + sum);
        printMessage("Hello, world!");
    }
}
