Java Programming - Exceptions - Discussion
Discussion Forum : Exceptions - Pointing out the correct statements (Q.No. 1)
1.
import java.io.*;
public class MyProgram
{
public static void main(String args[])
{
FileOutputStream out = null;
try
{
out = new FileOutputStream("test.txt");
out.write(122);
}
catch(IOException io)
{
System.out.println("IO Error.");
}
finally
{
out.close();
}
}
}
Answer: Option
Explanation:
Any method (in this case, the main() method) that throws a checked exception (in this case, out.close() ) must be called within a try clause, or the method must declare that it throws the exception. Either main() must declare that it throws an exception, or the call to out.close() in the finally block must fall inside a (in this case nested) try-catch block.

You both are right. While close() on FileOutputStream class object can also throw IOException we need to either catch it in try catch block inside finally or indicate the method itself throws IOException.

out.close() can be written in finally block

I think closing of file can also be done in finally block also.
