Question

String[] grain= {"1.油条","2.小米","3.高粱米","4.挂面","5.米粉","6.杂豆","7.土豆粉","8.地瓜粉","9.黑米","10.馒头"};
创建了一个数组，如何通过键入来查询 并打印出结果，例如：键入 油条 ，结果就显示1.油条

或者有其他的能实现键入查询方式也可以

Answer 1

import java.util.Scanner;
public class Test {
    public static void main( String args[]){
        String[] grain= {"1.油条","2.小米","3.高粱米","4.挂面","5.米粉","6.杂豆","7.土豆粉","8.地瓜粉","9.黑米","10.馒头"};
        System.out.println("请输入：");
        Scanner in=new Scanner(System.in);
        String str=in.next();
        boolean flag=true;
        for (String string:grain) {
            String name = string.split("\\.")[1];
            if (string.contains(name)){
                System.out.println(string);
                flag=false;
                break;
            }
        }
        if (flag){
            System.out.println("没有查找到！");
        }
    }
}
