Question

I have a condition like this

String str = null;

try{
  ...
  str = "condition2";
}catch (ApplicationException ae) {
  str = "condition3";
}catch (IllegalStateException ise) {
  str = "condition3";
}catch (Exception e) {
  str = "condition3";
}

if(str == null){
  str = "none";
}

Now I want to sum up all str = "condition3"; in one line. As finally block runs always so that will not fulfill my needs. What else can be done.

Beginning in Java 7, you can catch multiple exception types in a single catch block. The code looks something like this:

String str = null;

try {
    ...
    str = "condition2";
} catch (ApplicationException|IllegalStateException|Exception ex) {
    str = "condition3";
}

BTW: The code you’ve posted, as well as my Java 7 code could all be collapsed into simply catch (Exception e), because Exception is a superclass of both ApplicationException and IllegalStateException.
