Q17. Which of the following can fill in the blank in this code to make it compile? (Select 2 options.)
A. On line 1, fill in throws
B. On line 1, fill in throws new
C. On line 2, fill in throw new
D. On line 2, fill in throws
E. On line 2, fill in throws new
Answer: A,C
Explanation:
Option A and C are the correct answer.
In a method declaration, the keyword throws is used. So here at line 1 we have to use
option A.
To actually throw an exception, the keyword throw is used and a new exception is created,
so at line 2 we have to use throw and new keywords, which is option C. Finally it will look
like;
public void method() throws Exception {
throw new Exception0;
}

The correct answer is: On line 1, fill in throws. On line 2, fill in throw new
