Method Arguments in Java

Arguments are values passed to methods when they are called.

Example

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

printMessage("Hello Java!");

Pass by Value

• In Java, method arguments are always passed by value.
• For objects, the reference is passed by value.

Varargs (Variable Arguments)

public void printNumbers(int... nums) {
    for (int n : nums) {
        System.out.println(n);
    }
}

printNumbers(1, 2, 3, 4);
