  1. In Topic: displaying a key in a hashmap

    Posted 4 Aug 2015

    Quote

    1.I have the key "two" twice in my hashtable, while printing it is displayed "two" only once.Why its not displaying "two" twice?

    Because a Map does not permit duplicate keys (see API docs)

    Quote

    2.How to selectively display the key "two"?

    You can't really without iteration. But looking again at this question, i've a feeling that you are under the impression that a Map is simply a collection of name/value pairs. It isn't really. It's a collection that permits a lookup of a value by a key.
  2. In Topic: JComboBox Popup menu clipping issue

    Posted 3 Aug 2015

    Good article on this here:

    I put that balance += num. But nothing happens.

    What do you expect to happen?
  4. In Topic: Countdown timer outputted in png

    Posted 3 Aug 2015

    Quote

    is there any way I could used these with the image.buffered class to render out each number the timer yeilds as a png photo


    Why would you choose to display something inherently dynamic using something inherently static?

    num=Integer.parseInt(DataIn.readLine());
    


    a. 'num' is not a good name for that variable. It should be something like deposit
    b.
    deposit = Integer.parseInt(dataIn.readLine());
    balance += deposit;
    

    would do what you intend
    c. variable names in Java begin lower case and are in camel case
