HI All,
I came across this question in an interview, how do you make a HashMap as index based like ArrayList. for example the way you insert the elements in the HashMap has to be same as the Way you retrieve elements in the HashMap.
The Answer given by me is "always return the same hashCode so that hashCollision occurs and all the elements will be saved in same bucket." still its not maintaing the index. is there any way to make HashMap index based.

as per my knowledge , if you want to maintain insertion order you can use java.util.LinkedHashMap
