我一直在研究一個程序,它有3個類,其中2個類有定時器以不同的時間間隔重複,一旦定時器的一個「週期」完成,它將引發一個字符串作爲返回的事件。第三類訂閱來自其他兩個計時器類的事件並將它們打印到屏幕上。它工作得很好!我如何訂閱募集活動並一起打印?
但我的問題是,它是單獨打印它們。比方說,第一個計時器類運行,然後每隔2分鐘提出一個「hello」,每秒一次提出另一個「dog」,每發生一次事件,它都會將提出的事件打印到控制檯。我希望它每秒鐘打印「hellodog」,並將第一個計時器(hello)的值存儲在專用字段中,所以即使計時器(較慢的2分鐘計時器)還沒有被解僱。當2分鐘計時器啓動時,它將更新值,無論新值是什麼,新值將被打印到屏幕直到它再次觸發。
如果它很混亂,我會很樂意澄清。其種類很難解釋。
