    Help using BlueJ

    Hi everyone, im in a bind at the moment. Im using a program called BlueJ and im rather new tot he game. The teach gave the class an assignment to program some kind of number program but i have not idea what im doing cause he isnt exactly a great teacher.
    I created the class and stuff called "Tester" but now i come to a roadblock where i need to alter the base code inside the program.

    It says...
    Now implement the class "Tester". This class tests if an integer is positive, negative or zero.
    - The class has just one attribute "number" of int type, which is to store an integer.
    -The class has a construtor, which sets "number" to zero, and these two methods:
    -setNumber(int) sets "number" to the parameter value passed to setNumber(int)
    -printResult() displays the number and the appropriate message:
    " is positive." or
    " is negative." or
    " is zero."

    Compile the project and create an object and name it "mytester".

    Call the setNumber(int) method and provide a positive integer, then call the printResult() method to verify if your code works.

    Repeat steps with a negative integer and also with zero.

    *** Any help with this will be greatly appreciated. Its a shame this is such a problem to me... cause while uses our class time to teach us scientific notation, we arnt learning the important stuff... which is how to do this stuff. Anyway, please, any help would be awesome

    Everyone here will help you, but like TV show "Jeopardy", everything has to be in the form of a question!

    So, give us what you've written already and then ask a specific question.
