输入输出实现密码流

JAVA上机实践之输入输出流与多线程

代码如下

---

PassWord.java

import java.io.*;
import java.util.Scanner;

public class PassWord {
    public static void main(String args[]) {
        boolean success = false;
        int count = 0;
        Console cons;
        String passwd;
        Scanner sc = new Scanner(System.in);
        while (true) {
            System.out.print("输入密码:");
            passwd = sc.next();
            count++;
            String password = new String(passwd);
            if (password.equals("tiger123")) {
                success = true;
                System.out.println("您第" + count + "次输入的密码正确!");
                break;
            } else {
                System.out.println("您第" + count + "次输入的密码" + password + "不正确");
            }
            if (count == 3) {
                System.out.println("您" + count + "次输入的密码都不正确");
                System.exit(0);
            }
        }
        if (success) {
            File file = new File("E:\\t\\password.txt");
            try {
                FileReader inOne = new FileReader(file);
                BufferedReader inTwo = new BufferedReader(inOne);
                String s = null;
                while ((s = inTwo.readLine()) != null) {
                    System.out.println(s);
                }
                inOne.close();
                inTwo.close();
            } catch (IOException exp) {
            }
        }
    }
}
