    Question Vectors

    Hello! First of all my name is Francesco and i'm new to Java and this forum.

    I have a test to take and i don't manage to do it alone.

    I'm hoping that someone can help me get thru it.My whole future depends on my exam

    This are the requests:

    I need to create a class named "Forza" with a method "Matrice" that does the next operations:
    1.Has the integers "n" and "m"
    2.Has a vector "v" with the dimensions "m"
    3.If the vector is composed of odd numbers or under 18, Exit
    4.Create a matrix with the dimension n X m where the first row is given by the V vector, the second row by the V vector multiplied by 2, the third one, V multiplied by 3 and so on.
    5.Write the matrix in output.

    Should be something like this:

    If the Vector is [3 5 9 1], the matrix to print is:
    3 5 9 1
    6 10 18 2
    9 15 27 3
    12 20 36 4
    15 25 45 5

    Hopefully i didn't posted in the wrong section.

    As i said...my future depends on this.Please help.Thank you!

    Default Re: Vectors

    No one is going to do this for you. I suggest you make the effort to get started, if you have a problem along the way post some code, a specific question about the code, full error messages if there are any, what behavior you expect, and if it is different the behavior you are getting. If you are completely confused, you can start here:

    My whole future depends on my exam
    Your future depends upon every choice you make, including trying to cheat to get someone to do the assignment for you.
