    Google should be the first place to look for definitions.

    For java specific stuff, look in the tutorial:
    The Really Big Index
    Trail: Learning the Java Language: Table of Contents (The Java™ Tutorials)
    If you don't understand my answer, don't ignore it, ask a question.

    public Month()

    }

    public void print()

    for(int i=0; i < months.length;i++)
    {
    System.out.println(months[i]);
    }
    }

    public void fibSeries()
    {
    fib[0] = 0;
    fib[1] = 1;
    for(int i=2;i<fib.length;i++)
    {
    fib[i] = fib[i-1] + fib[i-2];
    }

    for(int i=0;i<fib.lenght;++)
    {
    System.out.println(fib[i]);
    }
    }
    }

    There isn't a natural place to use a collection with purely numeric data.

    You could replace the int array: fib with an ArrayList, but the conversions from int to Integer would make the code unusual.
