class Book{
private String title;
private double price;
public Book(){}
public Book(String t,double p){
title = t;
price = p;
}
public void setTitle(String t){
title = t;
}
public void setPrice(double p){
price = p;
}
public String getTitle(){
return title;
}
public double getPrice(){
return price;
}
//setter、getter省略
public String getInfo(){
return "书名:" + title + ",价格:" + price;
}
}
public class TestDemo{
public static void main(String args[]){
Book book = new Book("Java开发,89.2");
System.out.println(book.getInfo());
}
}

引用 1 楼 jiaotuwoaini 的回复:

public class TestDemo{ public static void main(String args[]){ Book book = new Book("Java开发,89.2"); System.out.println(book.getInfo()); } 红色的部分应该是： Book book = new Book("Java开发",89.2); 谢谢
