Exception Question

[Piyush Jain]

I took SCJP on saturday. I posted this question on certfication results forum, but nobody seems to answer it there, so I am posting it here.

the questions were all ok, except one that i could not think an answer for.

I don't remember it completely, but there was a statement between the try and catch, and should be giving a compiler error. However, the question was a short answer one and value of a string variable was asked. it looked somethng like this:

public class Class
{
String counter = "";

void foo(int i){
try
{
if(i==0)
throw new Exception();
}

counter += "1";
catch
{
//some code
}
finally
{
//some code
}
}
public static void main(String [] args)
{
foo(1);
foo(0); //*****
}

}

what is the value of variable counter at //*****


according to me, the code should not compile since there is a statement between the try/catch.

any comments? if it really can't compile, how should i go forward telling SUN this thing? they should not be penalizing me for this question in that case.

If you're in the US, try this link:

Otherwise, select country from this page:

According to my testing, a statement between a try{} block and its associated catch(){} block will result in 2 compile-time errors:

'try' without 'catch' or 'finally'

'catch' without 'try'

You'll want to provide Sun with as much specific information as you can, but I also think it's important to isolate the problem in general terms like this...

public class TryCatch{
  public static void main(String[] args){
    int i = 0;
    try{
      i++;
    }
    //i--; //causes compile-time errors
    catch(Exception e){
      System.out.println("Exception: " + e);
    }
  }
}
