    You have to write [italic]import java.util.*[/italic] at the top of your source file.

    : I declare some variable
    : private Date birthDate;

    I wouldn't recommend using Date. It has other purpose than what you most likely would expect. The most of it is deprecated, as well.

    Look at Calendar and Time as well. Also, depending on what you want to do, it might be a good idea to write your own Date-class. That's what i did most of the times (well, once, and then just adjusted it a number of times). It's easier than you might think and also, you get to know the class very well as it will be adapted to your specific needs.

    Do you need help with the code?


    Kind Regards
    Konrad

    I am asking whether it's possible to have the basical idea of Java in around 1 month time .

    Yes.

    It depends on what how you define "basic" but, still, yes. F.i. the Data class written by oneself should take about a day or two to understand, comprehend, write and test (YMMV).
