I have a problem in putting duplicate keys in hastable.
In my application immediately after the user logs in successfully, i put his userid and sessionid in hashmap.
Let me explain the problem 1.user X logs in 2.userid and session id are put in hashmap 3.hashmap size is 1 4.again user X opens a new window and logs in (other window is still open) 5.again now the same userid but with different sessionid(as it is new browser) has been put in hashmap 6.it has over written that had happend in 2, size of the hashmap is still 1.end result, same user id but session id of 4/5 is put in. 7.now user Y logs in 8.now that userY's id and sessionid is put in hashmap,size increases to 2
can some one explain me what is happening in 5,why it is getting overwritten, We can insert duplicate keys in hashmap, Please help me in solving this.
