LogConf e = getLogs(el);
    //add it to list
 myEmpls.add(e);

Now how to iterate the list of objects and get the values from this objects. How to do this?

回答1:

You could just google this and you would find tons of solutions.. But here is the code:

for(LogConf element : myEmpls) {
  System.out.println(element.getValue());
}

You should also get used to define the type of the elements in the list:

List<LogConf> myEmpls = new ArrayList<LogConf>();

I know its been some time since this post was made. You can also use the Iterator.

              List myEmpls = new ArrayList();
              Iterator itr = myEmpls.iterator();

              while(itr.hasNext()) {   
                   LogConf Logobj = (LogConf) itr.next();
                   System.out.println(Logobj.getterName());
              }

Hope this helps someone.
