class Something{
void change(String ln,String fn){
ln="Khan";
f="Aamir";
}.

This method is doesn't do anything. You are just changing the parameters 'in' and 'fn'.
Your println() method prints the firstname and lastname not the parameters.
It should be:
class Something{
void change(){
Firstname="Khan";
Lastname="Aamir";
}
You don't use the parameters.

Strings are immutable. You cannot modify parameter through references. You have to create, and then return, new Objects type string.
