i have some doubts in this code.
As far as i understand "The Map interface maps unique keys to value means it associate value to unique keys which you use to retrieve value at a later date."
when we see the first output "System.out.println(m.get("k1"));" it printsthe hashcode and not the aiko
But this line prints the System.out.println(m.get(d1)); // #4 the dog key
As hashMap returns the value of the key then why its not returning in the first case..please explain how hashMap works..
thanks in advance
