    Default Please Help me to solve this algorithm for Java

    Begining of the task:

    Peter went to book store wanted to buy books (he prepared book titles before on piece of paper) so he can fill up his home library.
    If he came to book store during the weekend (non working days) he has to go back home without books as the book store is closed, if he came on any working day he will complete shoping.
    Use if command. We know that on his shelf cannot fit more than 9 new books, so Peter will fill up his basket until he reaches that number.
    Use one of the loops: For, While, Do While.
    When Peter filled up his basket he realize that the third book from array needs to change with book called "Programming". Pay attention on indexes of array of books that are on his paper.

    End of Task

    Please help me to solve this algorithm...
    We should come up with book titles on our own.
    Thank you very much for your help

    What have you tried?
    Do you have any specific java programming questions?
    If you don't understand my answer, don't ignore it, ask a question.

    I am starting to learn programming and so far we did not do any programs but only algorithms.
    So in my question is actualy task to make algorithm
    this is what I tried but the ansewer was, it is not good

    If(workingDay==true){
    inBookstore=“buyBooks“()
    string[]booksTobuy=newString[9];
    booksTobuy=["50 Shades","Emilly","Titanic","The Firm","The Third Twin","Baker Street","Biography of Mozzart",
    "Golden Hair","Zoo"];
    }
    If(nonWorkingday()){PeterStayHome();
    else"buyBooks"()
    for(i=0,˂=9,i++);
    while(atCashier)()
    string basket[i]= booksTobuy[i]
    nasket[3]="programiranje";
    kosara=[3] // goes for The Firm
    peterPay()
    }

    --- Update ---

    As far as I can see his questions are based on Java language

    question is actualy task to make algorithm
    Can you list the steps in the algorithm that are needed to solved the problem. Make the list in English. Do not try writing any java code yet. What you posted looks too much like code.

    When posting code, be sure to wrap it in code tags:


    [code]
    **YOUR CODE GOES HERE**
    [/code]

    to get highlighting and preserve formatting.
    If you don't understand my answer, don't ignore it, ask a question.

    Dear Norm
    That is the problem. Because where ever I look into algorithms, they do not have any code in it. But this professor is asking me to do it this way, so it sort of looks like code.
    this is the task and I can see you are the only one willing to help.
    Peter went to book store wanted to buy books (he prepared book titles before on piece of paper) so he can fill up his home library.
    If he came to book store during the weekend (non working days) he has to go back home without books as the book store is closed, if he came on any working day he will complete shoping.
    Use if command. We know that on his shelf cannot fit more than 9 new books, so Peter will fill up his basket until he reaches that number.
    Use one of the loops: For, While, Do While.
    When Peter filled up his basket he realize that the third book from array needs to change with book called "Programming". Pay attention on indexes of array of books that are on his paper.

    How would ypu write algorithm for it, baybe you put in comment what comand would you use.

    I like programming and looking forward into it but beggining is really tough. I am searching all over the internert and cannot find proper answer

    What did the professor say was wrong with it.

    he did not specify that is what makes me upset. Maybe I will request someone else for help. I am doing paid online curse in Croatia, and they did not provide me with any literature or anything he is just sending tasks.

    I think your teacher is looking for pseudo code to describe your algorithm. You can find some examples of pseudo code here.

    Try writing down your tasks on paper in the order you would do them, then try and convert the tasks into pseudo code. Once you have it looking like a logical process post it here and we can give some feed back.

    If your teacher is looking for pseudocode I don't know, but I do know you can't run the code you've posted, and that's even without following your logic.
    Why do you double quote some of your method names?
    It's not “buyBooks“(), but buyBooks()
    It's not while(atCashier)(), but while(atCashier()){
    and there are many more issues
