Java | Exception Handling | Question 8

Predict the output of the following program.

class Test
{   int count = 0;

    void A() throws Exception
    {
        try
        {
            count++;

            try
            {
                count++;

                try
                {
                    count++;
                    throw new Exception();

                }

                catch(Exception ex)
                {
                    count++;
                    throw new Exception();
                }
            }

            catch(Exception ex)
            {
                count++;
            }
        }

        catch(Exception ex)
        {
            count++;
        }

    }

    void display()
    {
        System.out.println(count);
    }

    public static void main(String[] args) throws Exception
    {
        Test obj = new Test();
        obj.A();
        obj.display();
    }
}

(A) 4
(B) 5
(C) 6
(D) Compilation error

Answer: (B)
Explanation: ‘throw’ keyword is used to explicitly throw an exception.
In third try block, exception is thrown. So, control goes in catch block.
Again, in catch block exception is thrown. So, control goes in inner catch block.
