Fragen zu Map (english)

[New Line Equity]

hi ..


I have some questions .. Please answer me as soon as possible

- how can I Declare a private instance variable and it unsorted map with integer keys and string values??

- how can I write constructor that initializes the class to an empty map ??

- how can I Write an instance method for some class that takes no arguments, and returns no value.

the method should simply enter the four entries

Amazing to see that people from all over the world come here to ask questions

But you do know that your questions can easily be answered by simply reading a tutorial on Java? These are very basic problems, therefore it would be nice of you if you showed us what you have done so far to solve them (that means, show us your code ).

Edit:
Well okay, nrg rendered my post useless.
