    Default Re: i need help with java source code

    Hi Daruga , i found the mistakes
    wrong: 1
    String Payment = "";
    String Payment

    in the main method don't declare two variables with same name and should be initialize before using. like
    pls change:
    String Payment="";
    String Payment1="";


    wrong: 2

    Total = Price Quantity;

    pls change :
    Total =Price * Quality;

    modified code:
