Analyze the following code:

```
public class Test {
public static void main(String[] args) {
try {
String s = "5.6";
Integer.parseInt(s); // Cause a NumberFormatException

int i = 0;
int y = 2 / i;
}
catch (Exception ex) {
System.out.println("NumberFormatException");
}
catch (RuntimeException ex) {
System.out.println("RuntimeException");
}
}
}
```
a. The program displays NumberFormatException.
b. The program displays RuntimeException.
c. The program displays NumberFormatException followed by RuntimeException.
d. The program has a compile error.

d. The program has a compile error.
catch (RuntimeException ex) should be specified before catch (Exception ex).
