今天的目标是菜单: B站/马士兵的项目菜单
package java1;import java.util.Scanner;public class Test {public static void main(String[] args) {while(true){ //3.加入死循环,让输入一直有System.out.println();System.out.println("--->项目功能如下:<---");System.out.println("--->1.展示书籍<---");System.out.println("--->2.上架书籍<---");System.out.println("--->3.下架书籍<---");System.out.println("--->4.退出应用<---");System.out.println();System.out.println("请输入编号:");//1.借助scanner类输入东西Scanner sc =new Scanner(System.in);int choice =sc.nextInt(); //2.录入数据if(choice==1){System.out.println(" 1.展示书籍");}if(choice==2){System.out.println(" 2.上架书籍");}if(choice==3){System.out.println(" 3.下架书籍");}if(choice==4){System.out.println(" 4.退出应用");break;//4.跳出死循环}}}
}
收获:
//1.借助scanner类输入东西
Scanner sc =new Scanner(System.in);int choice =sc.nextInt(); //2.录入数据while(true){ //3.加入死循环,让输入一直有break;//4.跳出死循环
今天任务完成每天加油哦
