try..catch flow???

[Sagar Sharma]

hi,
when i try to compile the following code i recieve errors in the lines marked with **. The error says that "Statement not reached".
Is it true that i cannot have any line of code in the "if" blocks after the respective exceptions are thrown. i.e. is it true that "throw" should be the last statement of the block.
Please clear this doubt....
Thanks

import java.io.*;
import java.net.*;
class temp48{
public static void main(String args[]){

try{
String a=null;
String b=null;
if (a==null){
throw new MalformedURLException();
** System.out.println("bypass exception 1");
}
if (b==null){
throw new IOException();
** System.out.println("bypass exception 2");
}
}
catch(MalformedURLException me){
System.out.println("exception 1 caught");
return;
}
catch(IOException ie){
System.out.println("exception 2 caught");
return;
}
finally{
System.out.println("in finally()");
}
System.out.println("out of try block");
}
}

Haven't run across this problem before, but it would seem correct that you can't have anything after the throw statement. Once you throw that exception, it is going to jump to the catch block if you have one, so anything after the throw statement would never get executed. The compiler is telling you that because it thinks you made an error, and this code should be outside of the block. This is just my thought, but it seems like that is what the compiler is doing.

You are absolutely correct. Once the exception is thrown the control is out of the try block so the remaining statements ( of that block) are never reached. And that's what the compiler cribs about!
