Get detail messages of chained exceptions Java

Question

I'd like to know how I could throw a "final" Exception, containing a detailed message with all the detailed messages of a number of chained exceptions.

For example suppose a code like this:

try {   try {     try {       try {         //Some error here       } catch (Exception e) {         throw new Exception("FIRST EXCEPTION", e);       }     } catch (Exception e) {       throw new Exception("SECOND EXCEPTION", e);     }   } catch (Exception e) {     throw new Exception("THIRD EXCEPTION", e);   } } catch (Exception e) {   String allMessages = //all the messages   throw new Exception(allMessages, e); } 

I'm not interested in the full stackTrace, but only in the messages, I wrote. I mean, I'd like to have a result like this:

java.lang.Exception: THIRD EXCEPTION + SECOND EXCEPTION + FIRST EXCEPTION

I think what you need is:

public static List<String> getExceptionMessageChain(Throwable throwable) {     List<String> result = new ArrayList<String>();     while (throwable != null) {         result.add(throwable.getMessage());         throwable = throwable.getCause();     }     return result; //["THIRD EXCEPTION", "SECOND EXCEPTION", "FIRST EXCEPTION"] }
