Finally method

[Abraham Lee]

Here is the code:
class X {
public static void main(String[] args) {
try {
int i = (-1 >> 65535) + 1;
int j = 5/i;
System.out.println("Something");
}
catch (Exception e) { System.exit(0);
}
finally { System.out.println("Finally");}
}
}
When I have run this code nothing is displayed.
I have thought that finally method is called no mather do we have or haven't Exception.
Can someone clarify this.
Thanks

Hi Abraham,
finally block is always executed...except for some situations like this....i.e.
System.exit(0);
For this situation, the control directly comes out of the program w/o executing anything further...not even finally.

Hi
This is the only way you could get away without executing the finally clause, now instead of System.exit, if you had return then guess what the finally would execute.
Hope this Helps!!!

Now see if you comment the System.exit(0),

class X {
public static void main(String[] args) {
try {
int i = (-1 >> 65535) + 1;
int j = 5/i;
System.out.println("Something");
}
catch (Exception e) { //System.exit(0);
System.out.println("Inside Catch");
}
finally { System.out.println("Finally");}
}
}
  

You will get catch statement as well as finally part is also executed.

You should look at the System class in the JavaDocs.
System.exit() causes the VM to shutdown/quit.

Abraham.
Just remember one thing, incase if there is any System.exit() method in your source code, then there is no chance that your finally will execute.

Guys.
I just want to clear my doubt on this matter.
"Does the 'return' word in the finally statement will ever affect the statement" If yes, then how?
