Question

What is output by the following code?

public static void stuff(int w) {
w -= 2;
}

public static void main(String a[]) {
int n = 2;
stuff(n);
System.out.print(n);
}


1. 0
2. 4
3. 1
4. 3
5. 2

Answer 1

The output is 2. The stuff() function receives a copy of n, changes it but the result is never used.
