checked exception

[swaraj gupta]

This is from KS && BB master exam:

import java.io.*;
class Hello
{
	public static void main(String args[]) throws IOException{
		FileInputStream fis=null;			
		try{
			fis=new FileInputStream("A.txt");
			int x=fis.read();	
		}catch(IOException e){
			System.out.println("IOExceptionException caught");
		}
		finally{
			fis.close();
			System.out.println("finally");
		}		
	}

}

Ans: The code fails to compile due to an error on line no.13. (But the code is working fine). The explanation given is you can't use a method that throws a checked exception in catch or finally blocks, such methods should be in try blocks.
Please let me know what should I conclude now..?

What is the question asked there?
Its because the close method throws an IOException. Also its always good to check that the reference is not null.

Question is asked as: Given that all the methods of FileInputStream throws an IOException, then which of the following is true(among given options):

And the answer is: The program fails to to compile due to an error at line 13.

Dear swaraj gupta, If you take a look to your main() method you will find it declare that it throw IOException beside the try/catch block in the method block. If you omit that throws clause in the main() method signature you will sure get a compile time exception because of using fis.close() in the finally block without nesting it in a try/catch block
But the code as you upload it will compile without errors.
