Analyze the following code.

Question

```
public class Test {
public static void main(String[] args) {
System.out.println(m(2));
}

public static int m(int num) {
return num;
}

public static void m(int num) {
System.out.println(num);
}
}
```
a. The program has a compile error because the two methods m have the same signature.
b. The program has a compile error because the second m method is defined, but not invoked in the main method.
c. The program runs and prints 2 once.
d. The program runs and prints 2 twice.

Answer 1

a. The program has a compile error because the two methods m have the same signature.
You cannot override the methods based on the type returned.
