Java線程併發性

Question

所以我想要一個線程不斷更新你有多少「黃金」，另一個線程會運行一個遊戲。

問題在於光標正在爲每個光標進行更改，我首先通過讓它們與睡眠不同步來固定它，但是當我希望用戶輸入文本時，它將轉到第一行。有人知道怎麼修這個東西嗎？

import java.awt.*; 
import java.lang.*; 
import java.util.*; 
import java.awt.Color; 
import hsa.Console; 


public class Money { 
    public static long gold = 0; 
    public static long rate = 1; 
    public static void main(String args[]) { 
     Console con = new Console (41, 100); 
     ThreadTest test1 = new ThreadTest(); 
     ThreadTest2 test2 = new ThreadTest2(); 
     test1.setConsole(con); 
     test2.setConsole(con); 
     test1.start(); 
     test2.start(); 
    } 
} 

public class ThreadTest extends Thread { 
    Console c; 
    public void setConsole(Console con) { 
     c = con; 
    } 
    public void run() { 
     try { 
      sleep(900); 
     } catch (InterruptedException e) { 
     } 
     c.println("Welcome to the world of grind\nThe goal of the game is to amass money and get stuff!\nWhat would you like to do?\n\n<q>uest | <s>hop | <i>nventory"); 
     c.setCursor(5,1); 
     String choice = c.readString(); 
     } 
} 

public class ThreadTest2 extends Thread { 
    Console c; 
    public void setConsole(Console con) { 
     c = con; 
    } 
    public void run(){ 
     do 
     { 
      Money.gold = Money.gold + 1*Money.rate; 
      c.setCursor(1,1); 
      c.print("You currently have: " + Money.gold + " gold"); 
      try { 
       sleep(1000); 
      } catch (InterruptedException e) { 
      } 
     } 
     while (true); 
    } 
}

聽起來好像您需要通過控制檯對象進行同步，以便只有一個線程可以一次使用它。例如你ThreadTest2：

public class ThreadTest2 extends Thread { 
    Console c; 
    public void setConsole(Console con) { 
     c = con; 
    } 
    public void run(){ 
     do 
     { 
      Money.gold = Money.gold + 1*Money.rate; 
      synchronized(c) { 
       c.setCursor(1,1); 
       c.print("You currently have: " + Money.gold + " gold"); 
      } 
      try { 
       sleep(1000); 
      } catch (InterruptedException e) { 
      } 
     } 
     while (true); 
    } 
} 

只要從所有線程的所有輸出控制檯是通過控制檯對象的同一實例，只要每個線程同步像上面的​​例子中，它應該解決這個問題。
