创建book类.并为其编写两个构造方法

程序没学好。不知道怎么写了，求帮助

package book;


public class Book {
private String title;
private String press;
private String ISBN;
private double price;
public String getTitle() {
return title;
}
public void setTitle(String title) {
this.title = title;
}
public String getPress() {
return press;
}
public void setPress(String press) {
this.press = press;
}
public String getISBN() {
return ISBN;
}
public void setISBN(String iSBN) {
ISBN = iSBN;
}
public double getPrice() {
return price;
}
public void setPrice(double price) {
this.price = price;
}
public Book() {
}
public Book(String bookTitle,String bookPress,String bookISBN,double bookPrice)
{
title=bookTitle;
press=bookPress;
ISBN=bookISBN;
price=bookPrice;

System.out.println(title);
System.out.println(press);
System.out.println(ISBN);
System.out.println(price);
}
}
