Java菜鸟遇到困难了
import java.util.ArrayList;
import java.util.Scanner;
public class Produce {
private String name;
private int count;
private int price;
public Produce() {
super();
}
public Produce(String name, int count, int price) {
super();
this.name = name;
this.count = count;
this.price = price;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public int getCount() {
return count;
}
public void setCount(int count) {
this.count = count;
}
public int getPrice() {
return price;
}
public void setPrice(int price) {
this.price = price;
}
// 输入商品信息方法
public static ArrayList<> Input() {
Scanner sc = new Scanner(System.in);
ArrayList<Produce> al = new ArrayList<Produce>();
String name;
int count, price;
System.out.println("输入商品名称：");
name = sc.nextLine();
System.out.println("输入商品数量：");
count = sc.nextInt();
System.out.println("输入商品单价：");
price = sc.nextInt();
al.add(new Produce(name, count, price));
System.out.println("添加商品成功");
return al;
}
// 查看
public static void Find(String name, ArrayList<Produce> al) {
for (Produce p : al) {
if (name.equals(p.getName())) {
System.out.println("你要查看的商品是：" + p.getName() + " 数量是："
+ p.getCount() + " 单价是：" + p.getPrice() + " 总价是："
+ (p.getCount() * p.getPrice()));
}
}
}
// 删除某个商品
public static void Del(String name, ArrayList<Produce> al){
for(int i = 0; i < al.size(); i++){
if(name.equals(al.get(i).getName())){
System.out.println("删除商品[" + al.get(i).getName() + "]成功");
al.remove(i);
break;
}
}
}
public static void main(String[] args) {
ArrayList<Produce> al = new ArrayList<Produce>();
al = Input();// 添加
Scanner sc = new Scanner(System.in);
System.out.println("输入要查看的商品名：");
String fname = sc.next();
Find(fname, al);
System.out.println("输入要删除的商品名：");
String dname = sc.next();
Del(dname, al);
}
}
为什么一直提示所有包含这个Produce单词的有错误 我的文件名也是这个
