Java get user details

I'm new to Java and I have to write a program to get user details which appear like this:

Author’s Details
****************
Name: J. Beans

YOB: 1969

Age: 41

Book Details

************

       Title: *Wonderful Java*
       ISBN: *978 0 470 10554 9*
       Publisher: *Wiley*

This is what I've done but it does not work, can anyone help me to find out the problem ?

import java.util.Scanner ;
public class UserDetails
{
public static void main(String args[]开发者_运维知识库)
{
    System scan = new Scanner(System.in);
    input sname, fname, born, title, isbn, publisher;
    System.out.print("Please enter author's surname:");
    sname = input.nextLine();
    System.out.print("Please the initial of author's first name:");
    fname = input.nextLine();
    System.out.print("Please enter the year the author was born:");
    born = input.nextLine();
    System.out.print("Please enter the author's book title:");
    title = input.nextLine();
    System.out.print("Please enter the book's ISBN:");
    isbn = input.nextLine();
    System.out.print("Please enter the publisher of the book:");
    publisher = input.nextLine;

    System.out.println("Author's detail");
    System.out.println("**********************");
    System.out.println("Name:" + fname + sname);
    System.out.println("YOB:" + born);
    System.out.println("Age" + born);
    System.out.println("Book Details");
    System.out.println("**********************");
    System.out.println("Title:" + "*" + title + "*");
    System.out.println("ISBN:" + "*" + isbn + "*");
    System.out.println("Publisher:" + "*" + publisher + "*");
  }
}

hi you just wrongly use classes.Your code shoul be

import java.util.Scanner;

public class UserDetails {
    public static void main(String args[]) {
        Scanner scan = new Scanner(System.in);
        String sname, fname, born, title, isbn, publisher;
        System.out.print("Please enter author's surname:");

        sname = scan.nextLine();
        System.out.print("Please the initial of author's first name:");
        fname = scan.nextLine();
        System.out.print("Please enter the year the author was born:");
        born = scan.nextLine();
        System.out.print("Please enter the author's book title:");
        title = scan.nextLine();
        System.out.print("Please enter the book's ISBN:");
        isbn = scan.nextLine();
        System.out.print("Please enter the publisher of the book:");
        publisher = scan.nextLine();

        System.out.println("Author's detail");
        System.out.println("**********************");
        System.out.println("Name:" + fname + sname);
        System.out.println("YOB:" + born);
        System.out.println("Age" + born);
        System.out.println("Book Details");
        System.out.println("**********************");
        System.out.println("Title:" + "*" + title + "*");
        System.out.println("ISBN:" + "*" + isbn + "*");
        System.out.println("Publisher:" + "*" + publisher + "*");
    }
}

Among other things, change this:

  System scan = new Scanner(System.in);
  input sname, fname, born, title, isbn, publisher;

to this:

  Scanner input = new Scanner(System.in);
  String sname, fname, born, title, isbn, publisher;

If you are really serious about learning how to program, follow everyone's recommendation and:

• Read books.
• Study tutorials.
• Use an IDE (Eclipse is a good one, and it's free to download)
• Practice a lot.
• Ask questions a lot.

Your code is full of syntax and semantic errors. This works:

 import java.util.Scanner ;
  public class UserDetails {
  public static void main(String args[])
  {
  Scanner scan = new Scanner(System.in);
  String sname, fname, born, title, isbn, publisher;
  System.out.print("Please enter author's surname:");
  sname = scan.nextLine();
  System.out.print("Please the initial of author's first name:");
  fname = scan.nextLine();
  System.out.print("Please enter the year the author was born:");
  born = scan.nextLine();
  System.out.print("Please enter the author's book title:");
  title = scan.nextLine();
  System.out.print("Please enter the book's ISBN:");
  isbn = scan.nextLine();
  System.out.print("Please enter the publisher of the book:");
  publisher = scan.nextLine();

  System.out.println("Author's detail");
  System.out.println("**********************");
  System.out.println("Name:" + fname + sname);
  System.out.println("YOB:" + born);
  System.out.println("Age" + born);
  System.out.println("Book Details");
  System.out.println("**********************");
  System.out.println("Title:" + "*" + title + "*");
  System.out.println("ISBN:" + "*" + isbn + "*");
  System.out.println("Publisher:" + "*" + publisher + "*");
  }
  }

You are close, but you have a couple errors and a typo.

System scan = new Scanner(System.in); This should be: Scanner scan = new Scanner(System.in); What you are doing here is creating a new object reference of type scanner named scan -- not System.

Next problem: input sname, fname, born, title, isbn, publisher; This is again, a declaration issue with types. Each of these variables is a string reference -- should declare this as; String sname, fname, born, title, isbn, publisher;

Lastly, you have a typo: publisher = input.nextLine; You forgot the () that indicate this is a function call. Should be: publisher = input.nextLine();

There may be some other more subtle issues, but this should get your code to compile and run at least :).
