    Need Help debugging errors form these programs number1!


    I am a C/C++ progammer, and am new at Java. I am spending 3 to 4 hours a day
    teaching my self; however I am at an impasse with debugging. The Java syntax
    is heafty, thus I have concluded that it's going totkae long to learn than
    what I anticipate.

    These programs were constructed according to the syntax from a Java programming
    book I purchased at Borden books. Still I am getting errors that I am at
    a lost correcting:

    Re: Need Help debugging errors form these programs number1!


    Can you post the error messages you get??
    I dont know which book you are reading but if those programs are from that
    book i wouldnt spend time reading it.
