Question 1

Given the following method

static void nPrint(String message, int n) {
while (n > 0) {

System.out.print(message);

n--;

}
}

What is k after invoking nPrint("A message", k)?

int k = 2;
nPrint("A message", k);

◦ 0
◦ 1
◦ 2
◦ 3

Question 2

Analyze the following code:

public class Test {
public static void main(String[] args) {

System.out.println(xMethod(5, 500L));

}

public static int xMethod(int n, long l) {

System.out.println("int, long");

return n;

}

public static long xMethod(long n, long l) {

System.out.println("long, long");

return n;

}
}

◦ The program displays int, long followed by 5.
◦ The program runs fine but displays things other than 5.
◦ The program displays long, long followed by 5.
◦ The program does not compile because the compiler cannot distinguish which xmethod to invoke.
