Query about break statement in java

Question

Hi All,
I am looking at some seeded oracle class and came across this code and wanted to understand what it does in the catch exception part ( in bold below).
Thanks
Shanky
protected String getOrgIdFromTransaction(OAPageContext oapagecontext, String s, String s1)
    String s2;
    String s3;
    StringBuffer stringbuffer;
    ViewObject viewobject;
    s2 = "-1";
    s3 = null;
    stringbuffer = (new StringBuffer(" select org_id")).append(" from ar_payment_schedules");
    if (s != null)
      stringbuffer.append(" where payment_schedule_id = :1");
      s3 = s;
    } else
    if (s1 != null)
      stringbuffer.append(" where customer_trx_id = :1");
      s3 = s1;
    viewobject = null;
    try
      viewobject = oapagecontext.getRootApplicationModule().createViewObjectFromQueryStmt("CustSiteForInvoiceVO", stringbuffer.toString());
      viewobject.setWhereClauseParam(0, s3);
      Object obj = null;
      viewobject.executeQuery();
      while (viewobject.hasNext())
        Row row = viewobject.next();
        s2 = row.getAttribute(0).toString();
      viewobject.remove();
    catch (Exception exception)
      throw OAException.wrapperException(exception);
    * viewobject.remove();  // when does this part and below get executed ? *
    *break MISSING_BLOCK_LABEL_176 ; // where is this label ? *
    *Exception exception1;*  // define a variable of type Exception
    *exception1;  // what does this do ? *
    viewobject.remove();
    *throw exception1;*  // why throw this ?
    return s2;
  }

Thanks Shekhar.
I have read that and understand the break statement. But I cannot see a label mentioned in my code sample.
Where is that label ? Oracle have used this in many places.
Any ideas ?
