第6次Java作业

一，年会找座位

package 第六次作业;

import java.util.Scanner;

public class t1 {
	public static void main(String[] args) { //主函数
		System.out.println("请输入要查询的姓名：");//输入文字
		Scanner scanner = new Scanner(System.in);  //从键盘获取输入的值放入scanner  
		String a = scanner.next(); //把输入的汉字赋值给a变量 
	switch (a) {//指定switch语句的表达式为变量a
	case "张龙":
	System.out.println("您是一号桌");break;//输出结果
	case "赵虎":
	System.out.println("您是二号桌");break;//输出结果
	case "王潮":
	System.out.println("您是三号桌");break;//输出结果
	}
	}
}

 二，屏蔽手机号中间数字

package 第六次作业;

import java.util.Scanner;

public class t2 {

	public static void main(String[] args) {
		System.out.println("请输入手机号码:");
		try (Scanner scanner = new Scanner(System.in)) {
			String num = scanner.next();
			String a1=num.substring(0,3);
			String b=num.substring(7);
			System.out.println("手机号"+num+"屏蔽后的效果："+a1+"****"+b); //输出结果
		}
	}

}

 三，模拟商品入库功能

package 第六次作业;
import java.util.Scanner;
public class t3 {
public static void main(String[] args) {
		// TODO Auto-generated method stub
		System.out.println("请输入商品编号:");
		try (Scanner scanner = new Scanner(System.in)) {
		String a = scanner.next();  
		System.out.println("请输入商品名称:");
		try (Scanner scanner2 = new Scanner(System.in)) {
		String b = scanner.next(); 
		System.out.println("请输入商品规格:");
		try (Scanner scanner3 = new Scanner(System.in)) {
		String c = scanner.next(); 
		System.out.println("请输入商品价格:");
		try (Scanner scanner4 = new Scanner(System.in)) {
		String d = scanner.next(); 
		System.out.println("请输入商品数量:");
		try (Scanner scanner5 = new Scanner(System.in)) {
		String e = scanner.next(); 
		System.out.println("商品入库单");
		System.out.println("  商品编号为:"+ a);
		System.out.println("  商品名称为:"+ b);
		System.out.println("  商品规格为:"+ c);
		System.out.println("  商品价格为:"+ d);
		System.out.println("  商品名称为:"+ e);
		System.out.println("    保存   取消");
		}}}}}}} 
	  

 四，时时更新导航菜单

package 第六次作业;

import java.util.Scanner;

public class t4 {

	public static void main(String[] args) {
		// TODO Auto-generated method stub
		String a =("天猫 聚划算 天猫超市 | 淘抢购 司法拍卖 淘宝心选 兴农扶贫 | 飞猪旅行");//创建一个字符串
		System.out.println("天猫 聚划算 天猫超市 | 淘抢购 司法拍卖 淘宝心选 兴农扶贫 | 飞猪旅行");
		System.out.println("请选择要被替换的菜单:");
		try (Scanner scanner1 = new Scanner(System.in)) {
		String c = scanner1.next();
		System.out.println("请输入新的菜单:");
		try (Scanner scanner2 = new Scanner(System.in)) {
		String d = scanner2.next();
		String b= a.replace(c,d);
		System.out.println("被替换后的菜单："+"n" +b);
	}

}}}

 五，模拟输出中国联通流量提醒

package 第六次作业;

import java.util.Date;
public class t5 {
	public static void main(String args[]) {
		float u = 3.59f ;
		float h = 3.40f ;
		String d = "http://u.10010.cn/tAE3v";
		Date date = new Date();
		String month = String.format("%tm", date);
		String day = String.format("%td", date);
		String hour = String.format("%tH",date);
		System.out.println("中国联通流量提示：");
		System.out.println("截止"+ month +"月"+ day +"号"+ hour +"时");
		System.out.println("您的共享通用流量已用"+ u +"GB剩余流量为"+ h +"GB");
		System.out.println("如需查询流量详情，亲您登陆"+ d +"进行查询");
	}
 
}
