Accessing objects stored in an array list or set

[kev3kev3]

Hi,

If someone can set me straight on this it would be much appreciated...

Basically I have a treeSet or an ArrayList and they are storing employee objects which contain various information such as name, age, employee id, continuous service, etc.

Once I have say 5 employees created and stored how do I then print all the information stored in the treeSet or ArrayList, by this i mean print out the information stored about each employee...?

At the minute all i can manage to print out is some random text which i think might be the location the employees are stored..

Thanks for any help in advance....

how do I then print all the information stored in the treeSet or ArrayList,

Get the objects out of the container one by one and call a method in the object that will either do the printing or will return a String that is formatted for printing.

Ok, so if i was to use a toString method in my employee object. Problem I have is that the employee object is created through a number of classes so for example I have a person class which stores name, age etc. then I have a subclass manager which stores managerial information and inherits the name age etc from the person class. If i create a toString method in my manager class i don't know how to state the name, age, etc in in the toString method there.

Where is the data that you want the toString() method to use to build the String it returns?
It will have to go to where that data is located.

Adding to what Norm says, if you do create a toString() method you can then just println(yourSet).
If the output from that is not sufficient for you then you'll have to loop over the set, of course.

Thanks guys seem to have this working now, 1 small issue is that I am using blue J and the terminal window the output is printed to cuts off the start of the information as it only seems to want to display a certain amount of information and cuts off the rest is there any way to fix this so I can check that all the info printed is okay...?

there was an option called unlimited buffering which seems to have sorted this.

Mega thanks for your help guys...
