我該如何讓Java每秒鐘都添加到私人int mouseClicks？

Question

public class Blank extends WindowController 
{ 
    private int mouseClicks; 

    public void onMousePress(Location point) 
    { 
     mouseClicks++; 
    } 
} 

我的目標是，如果mouseClicks每秒增加一次，而只需點擊一次啓動它。

Answer 1

研究使用Thread.sleep(1000);暫停執行一秒鐘。

Answer 2

您可以測試以來的最後一次點擊通過的時間。

long lLastClickTime = Long.MIN_VALUE; 

public void onMousePress(Location point) { 
    final long lCurrentTime = System.currentTimeMillis(); 
    if(lCurrentTime - lClickLastTime >= 1000) { 
     mouseClicks++; 
     lLastClickTime = lCurrentTime; 
    }   
} 

Answer 3

這是我可以得到的最佳解決方案。

public class Blank extends WindowController 
{ 
    private final AtomicInteger mouseClicks = new AtomicInteger(); 
    private boolean hasStarted = false; 

    public void onMousePress(Location point) 
    { 
     if(!hasStarted){ 
     hasStarted = true; 
     Thread t = new Thread(){ 
      public void run(){ 
       while(true){ 
        mouseClicks.incrementAndGet(); //adds one to integer 
        Thread.sleep(1000); //surround with try and catch 
       } 
      } 
     }; 
     t.start(); 
     } 
    } 
}
