Insertion Sort Based On Two Attributes

public class Employee {
private String firstName;
private String eeid;
}

I want to sort using empoyee firstName.. If two employee names are same, i need to sort based on eeid.. using insertion sort

if (key == "name") {
for (int i = 1; i < list.length; i++) {
Employee t = list[i];
int j;
for (j = i - 1; j >= 0 && t.getLastName().compareTo(list[j].getLastName())<0; j--)
list[j + 1] = list[j];
list[j + 1] = t;
}
}

It will sort using names.. But if two names are same, it wont sort based on eeid.. I want to achieve only using insertion sort..

EX:

vivek 8
broody 2
chari 3
vivek 5
chari 1

output:

broody 2
chari 1
chari 3
vivek 5
vivek 8
