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
