随机点名器

练习一：

public class Test1 {public static void main(String[] args) throws IOException {//"C:\\Users\\20724\\Desktop\\name.txt","UTF-8"//创建读取流BufferedReader br = new BufferedReader(new FileReader("C:\\Users\\20724\\Desktop\\name.txt"));//读取的数据使用list集合进行存储ArrayList<String> list = new ArrayList<>();String str;while ((str = br.readLine()) != null){list.add(str);}br.close();//随机数获取要的名字Random r = new Random();int index = r.nextInt(list.size());String s = list.get(index);System.out.println("选中的同学的名字为："+s.split("-")[0]);}
}

练习二：

public class Test2 {public static void main(String[] args) throws IOException {//"C:\\Users\\20724\\Desktop\\name.txt","UTF-8"//创建读取流BufferedReader br = new BufferedReader(new FileReader("C:\\Users\\20724\\Desktop\\name.txt"));//读取的数据使用list集合进行存储ArrayList<String> list = new ArrayList<>();String str;while ((str = br.readLine()) != null){list.add(str);}br.close();for (int i = 0; i < 1000000; i++) {String name =  RannderName(br,list);System.out.println(name);}}private static String RannderName(BufferedReader br,ArrayList<String> list) throws IOException {//随机数获取要的名字Random r = new Random();//随机数确定要的是男还是女int inderSex = r.nextInt(10)+1;String s;if (inderSex<=7){while (true) {//抽男生int index = r.nextInt(list.size());s = list.get(index);//判断是否为男生String[] split = s.split("-");if (split[1].equals("男")){//是男生break;}}}else {while (true) {//抽男生int index = r.nextInt(list.size());s = list.get(index);//判断是否为女生String[] split = s.split("-");if (split[1].equals("女")){//是女生break;}}}String name = "选中的同学的名字为："+s;return name;}}

}

练习四：

public class Test4 {public static void main(String[] args) throws IOException {//"C:\\Users\\20724\\Desktop\\name.txt","UTF-8"//创建读取流，两个读取流每次运行将这两个都读取出来BufferedReader br = new BufferedReader(new FileReader("C:\\Users\\20724\\Desktop\\name.txt"));BufferedReader Runnum = new BufferedReader(new FileReader("C:\\Users\\20724\\Desktop\\demo\\javase2day01\\javaseday30\\b.txt"));//读取的数据使用list集合进行存储ArrayList<String> list = new ArrayList<>();ArrayList<String> next = new ArrayList<>();String str;while ((str = br.readLine()) != null){list.add(str);}br.close();String str2;while ((str2 = Runnum.readLine()) != null){next.add(str2);}Runnum.close();//先进行判断是否已经读取一轮if (list.size()==next.size()){//清空已选文件BufferedWriter bw = new BufferedWriter(new FileWriter("C:\\Users\\20724\\Desktop\\demo\\javase2day01\\javaseday30\\b.txt"));bw.close();return;}Random r = new Random();//获取的名字String s;//随机数获取要的名字while (true) {int index = r.nextInt(list.size());s = list.get(index);//判断已选文件中有没有这个名字if (next.contains(s)){continue;}System.out.println("选中的同学的名字为："+s.split("-")[0]);break;}//写入数据BufferedWriter writer = new BufferedWriter(new FileWriter("C:\\Users\\20724\\Desktop\\demo\\javase2day01\\javaseday30\\b.txt", true));writer.write(s);writer.newLine();writer.close();}
}

练习五：

public class Demo5 {public static void main(String[] args) throws IOException {//带权重的随机BufferedReader br = new BufferedReader(new FileReader("javaseday30\\a.txt"));//将数据存入Student对象存入集合中ArrayList<Student> list = new ArrayList<>();String str;while ((str = br.readLine()) != null){String[] split = str.split("-");Student student = new Student(split[0],split[1],Integer.parseInt(split[2]),Double.parseDouble(split[3]));list.add(student);}br.close();//获取总的权重和double weight = 0;for (Student student : list) {weight += student.getWeight();}//计算每个对象的权重，并存入数组中double[] arr= new double[list.size()];int count = 0;for (Student student : list) {arr[count] = student.getWeight()/weight;count++;}//计算各个区间的数据for (int i = 1; i < arr.length; i++) {arr[i] = arr[i] + arr[i-1];}//进行随机得到0-1之间的随机数double random = Math.random();
//        System.out.println(random);//判断random在arr 中的位置//使用二分法查找,使用Arrays.binarySearch方法得到的返回值是 -插入点-1 = f//据此获取位置int i = Arrays.binarySearch(arr, random);int index = -i-1;
//        System.out.println(index);//根据索引获取数据System.out.println("抽到的数据是： "+list.get(index).toString());//修改权重为2分之1；list.get(index).setWeight(list.get(index).getWeight()/2);//将数据写会文件中BufferedWriter bw =  new BufferedWriter(new FileWriter("javaseday30\\a.txt"));for (Student student : list) {bw.write(student.toString());bw.newLine();}bw.close();}
}

登录注册

练习一

public class Test1 {public static void main(String[] args) throws IOException {//链接BufferedReader br = new BufferedReader(new FileReader("javaseday30\\userinfo.txt"));//将数据读取到list集合中ArrayList<User> list = new ArrayList<>();String str;while ((str = br.readLine())!=null){//拆解字符串得到数据String[] split = str.split("&");String[] split1 = split[0].split("=");String[] split2 = split[1].split("=");User user = new User(split1[1],split2[1]);list.add(user);}Scanner sc = new Scanner(System.in);System.out.println("请输入用户名");String name = sc.next();System.out.println("请输入密码");String password = sc.next();boolean flag = true;//遍历集合判断是否正确for (User user : list) {if (user.getName().equals(name)){if (user.getPassword().equals(password)){System.out.println("登录成功");flag = false;}}}if (flag){System.out.println("账号和密码错误");}}
}

public class User {private String name;private String password;public User() {}public User(String name, String password) {this.name = name;this.password = password;}/*** 获取* @return name*/public String getName() {return name;}/*** 设置* @param name*/public void setName(String name) {this.name = name;}/*** 获取* @return password*/public String getPassword() {return password;}/*** 设置* @param password*/public void setPassword(String password) {this.password = password;}public String toString() {return "User{name = " + name + ", password = " + password + "}";}
}

练习二：

public class Test2 {public static void main(String[] args) throws IOException {//链接BufferedReader br = new BufferedReader(new FileReader("javaseday30\\userinfo.txt"));//将数据读取到list集合中HashSet<User> list = new HashSet<>();String str;while ((str = br.readLine())!=null){//拆解字符串得到数据String[] split = str.split("&");String[] split1 = split[0].split("=");String[] split2 = split[1].split("=");String[] split3 = split[2].split("=");int i = Integer.parseInt(split3[1]);User user = new User(split1[1],split2[1],i);list.add(user);}Scanner sc = new Scanner(System.in);System.out.println("请输入用户名");String name = sc.next();System.out.println("请输入密码");String password = sc.next();boolean flag = true;//遍历集合判断是否正确for (User user : list) {if (user.getName().equals(name)){//判断是否登录超过3次if (user.getCount()>=3){System.out.println("您已经连续输错三次密码，请与相关人员联系");flag = false;//修改登录次数int n = user.getCount()+1;user.setCount(n);//写入文件BufferedWriter bw = new BufferedWriter(new FileWriter("javaseday30\\userinfo.txt"));for (User user1 : list) {bw.write(user1.toString());bw.newLine();}bw.close();return;}if (user.getPassword().equals(password)){System.out.println("登录成功");flag = false;//登录成功则将登录次数置为0int n = 0;user.setCount(n);//写入文件BufferedWriter bw = new BufferedWriter(new FileWriter("javaseday30\\userinfo.txt"));for (User user1 : list) {bw.write(user1.toString());bw.newLine();}bw.close();}else {//修改登录次数int n = user.getCount()+1;user.setCount(n);//写入文件BufferedWriter bw = new BufferedWriter(new FileWriter("javaseday30\\userinfo.txt"));for (User user1 : list) {bw.write(user1.toString());bw.newLine();}bw.close();}}}if (flag){System.out.println("账号或密码错误");}}
}

修改了USer类，添加了登录次数和toString方法。

public class User {private String name;private String password;private int count;public User() {}public User(String name, String password, int count) {this.name = name;this.password = password;this.count = count;}/*** 获取* @return name*/public String getName() {return name;}/*** 设置* @param name*/public void setName(String name) {this.name = name;}/*** 获取* @return password*/public String getPassword() {return password;}/*** 设置* @param password*/public void setPassword(String password) {this.password = password;}/*** 获取* @return count*/public int getCount() {return count;}/*** 设置* @param count*/public void setCount(int count) {this.count = count;}public String toString() {return "username="+name+"&password="+password+"&count="+count;}
}
