Question 3
Multiple choice

Which three are advantages of the Java exception mechanism?

Improves the program structure because the error handling code is separated from the normal program function

B.

Provides a set of standard exceptions that covers all the possible errors

C.

Question 5
Multiple choice

Given:

class Mid {

public int findMid(int n1, int n2) {

return (n1 + n2) / 2;

}
