Hi,
This was a question from whizlabs:
The Bold words are what i have filled in the code


This code Compiles fine and output is sorted by name and age of employees.

At the line where i have marked 1 instead of :
public int compare(T obj1, T obj2)//1
I made it
public int compare(Employee obj1, Employee obj2)//1

That means i used Employee instead of T.
The output of both the programs is same
I wanted to konw that is it wrong to do this in the exam?

This does not compile:
public int compare(Employee obj1, Employee obj2)//1

My compiler says:
The type MyComparator<T> must implement the inherited abstract method Comparator<T>.compare(T,T).

Sara,

public int compare(Employee obj1, Employee obj2)//1
It compiles fine in JDK 1.5 and the output is :
------------------
Daisy of age 22
Daisy of age 40
George of age 29
Jacob of age 30
-----------------=

Ok strange, cause I pasted your code in Eclipse, and compiled it with version 1.5 and it does not compile:-)
