Java — Method Parameters

Basic parameters

public static void greet(String name) {
    System.out.println("Hello, " + name);
}

greet("Alice");

Multiple parameters

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

int result = add(5, 3);

Varargs

public static int sum(int... numbers) {
    int total = 0;
    for (int n : numbers) {
        total += n;
    }
    return total;
}

sum(1, 2, 3, 4, 5);

Mini Practice

1. Create method with parameters
2. Use multiple parameters
3. Practice varargs
4. Return values
