Hello there fellow java users, I'm dealing with some situations with Java Eclipse, I was writing the codes for a public class related to 'books". basically using instance data for the author, publisher, copy right date, etc. I feel like I've got all the correct codes and everything but I feel as if I've stumbled onto a certain error that I can't fix. Every-time I try to run the program the console output says: book[Java Application] C:\Program Files (x86)\Java\jre7\bin\javaw.exe. I don't know what I did wrong, if anybody can help me that would be great. Here are the codes i wrote:

package book;
public class book {
public static void main(String[] args){

}
        private String title;
        private String author;
        private String publisher;
        private int copyRightDate;


        public book(String authorName, String publisher, String author, String year22) {


            title = getTitle();
            author = getAuthor();
            publisher = getPublisher();
            copyRightDate = year2();
            }
            private int year2() {
            return 0;
        }
            public book(String authorName, String publisher2, String author2,
                int year32) {
        }
            public book()
        {
            author = "Ridley Pearson";

            title = "Kingdom Keepers";
            publisher = "Disney";

        }
        public void setAuthor(String authorName) {
            author = authorName; }
                public String getAuthor() {

            return author; }

         public void setTitle(String bookTitle) {
            title = bookTitle; }

        public String getTitle() {
            return title; }

        public void setPublisher(String publisherName) {
            publisher = publisherName; }
        public String getPublisher() {
            return publisher;}
        public void setCopyRightDate(int date) {

            copyRightDate = date; }

        public int getCopyRightDate() {
            return copyRightDate; }

        public String toString() {
           return (title + "\\t" + author + "\\t" + publisher + "\\t" + copyRightDate);}

public class bookshelf{
}
public void main1(String[] args) {
