Timeunit未在第二類中解析

Question

我試圖創建一個具有基於時間的元素的遊戲時遇到問題。其中，我已經給了用戶300秒來猜測一個數字。

如果玩家用完了時間，那麼代碼將停止我創建的while循環，並打印出用戶耗盡的時間。

但是 - 代碼甚至不解析While循環。它會直接跳到用戶耗盡時間，而我找不到任何修復程序。

這是我的主要類別：

import java.util.Scanner; 
import java.util.Random; 
import java.util.concurrent.TimeUnit; 

public class start { 
public static void main(String[] args) throws InterruptedException { 
    Random random = new Random(); 
    Scanner reader = new Scanner(System.in); 
    byte Lives = 10; 

    System.out.println("Hey there, and welcome to my Guessing game!"); 

    TimeUnit.MILLISECONDS.sleep(1000); 

    System.out.println("I'm thinking of a number between 1 and 100"); 

    int Guessed_Number = random.nextInt(100 - 1); 

    TimeUnit.MILLISECONDS.sleep(1000); 

    System.out.println("You have 10 lives!"); 
    System.out.println(""); 
    System.out.println("Ready? When you start, you will have 5 minutes to complete the game"); 
    int LocalTime = Time.Time; 
    System.out.println(LocalTime); 
    boolean Win = true; 
    while(Lives>0 & Win & LocalTime > 0) 
    { 
     try { 
     System.out.println("I'm thinking of a number between 1 and 100"); 
     System.out.println("Guess the number I'm thinking of!"); 
     System.out.println("You have " + Lives + " Lives remaining"); 
     byte Guess = reader.nextByte(); 
     if(Guess > Guessed_Number) 
     { 
      System.out.println("Your number is too big!"); 
      Lives--; 
     } 
     else if(Guess < Guessed_Number) 
     { 
      System.out.println("Your number is too small!"); 
      Lives--; 
     } 
     else if(Guess == Guessed_Number) 
     { 
      System.out.println("You have guessed my number correctly!"); 
      System.out.println("My number was " + Guessed_Number); 
      System.out.println("Welldone! You had " + Lives + " Lives remaining!"); 
      Win = false; 
     } 
     else 
     { 
      System.out.println("Odd. Something weird happened. Try again!"); 
     } 
     } 
     catch (Exception error) 
     { 
      System.out.println("Error!"); 
      System.out.println("Please try to only put in numbers"); 
      TimeUnit.MILLISECONDS.sleep(1000); 
      reader.next(); 
     } 
    } 
    if(LocalTime == 0) 
    { 
     System.out.println("You ran out of time! Try again!"); 
     System.out.println("The number I was thinking of was " + Guessed_Number); 
    } 
    else if(Lives ==0) 
    { 
     System.out.println("You ran out of lives! Try again!"); 
     System.out.println("The number I was thinking of was " + Guessed_Number); 
    } 
    else 
    { 
     System.out.println("Foobar! The code ran into a error while working"); 
     System.out.println("Please contact me at JordonMyers123@Gmail.Com with the Error code FOOBAR and I'll try and fix it."); 
    } 
} 

} 

這裏是我的第二類，我專門只運行While循環的時間因素。

import java.util.concurrent.TimeUnit; 

public class Time extends InterruptedException { 
private static final long serialVersionUID = 1L; 
public static final int Time = 0; 

{ 
int Time = 300; 
while(Time > 0); 
{ 
    Time = Time - 1; 
     TimeUnit.SECONDS.sleep(1); 
} 
} 
}

由於本地時間是零，你的循環需要本地時間> 0

int LocalTime = Time.Time; 

指向名爲「時間」

public static final int Time = 0; 

不是局部變量也稱爲「時間的靜態變量'

int Time = 300;
