Hi Jkid, I have attached three files with the mail which will help explain you the Comparator behaviour
Employee.java -- Bean for storing Employee data
Name.java -- Name class used in sun tutorial
TestEmployee.java -- A test class explaining the comparator code.(Here
the comparison of Employee objects is done by using the date)
I have used only date , but you can use multiple criteria like number
.. try it yourself
Thanks,
Ashok A V
