sorting of atributes of userdefined array object

[deepali.bhosale]

hi,
I have an array of Student Object. Student has name, age and phone number attribute. I need to sort this array on the basis on name ,age and Phone number .
How to do that.
I have read about Arrays.sort().
But how to apply this on Student arrays' attributes.
plz help...
Thanks in advance

Two options, either have the student object implement the comparator interface thus defining the compare(o1, o2) method. It would something like this:

class Student implements Comparator<Student> {
....
}

Or you can create a stand alone comparator class/code block and pass that as a second parameter to sort.

It's probably worth the first approach if you want students sorted in other areas too.
