Java - checking if parseInt throws exception

Question

I\'m wondering how to do something only if Integer.parseInt(whatever) doesn\'t fail.

More specifically I have a jTextArea of user specified values seperated by line

You can use the try..catch statement in java, to capture an exception that may arise from Integer.parseInt().

Example:

try {
  int i = Integer.parseint(stringToParse);
  //parseInt succeded
} catch(Exception e)
{
   //parseInt failed
}
