Stage的run方法里有armyOfFarmer.join();這句。這句的意思是說農民的run方法執行完了才能往armyOfFarmer.join();這句代碼之后運行。但你看看你的ArmyRunnable的run方法里，while?(keepRunning)的keepRuning一直是true，while循環沒有被終止。所以發生了死鎖。
把Stage的run方法里的armyTaskOfFarmer.keepRunning=false;這句代碼修改到armyOfFarmer.join();這句代碼之前，就不會發生死鎖了。
下面是我修改之后的代碼

沒注意還有個這個KeypersonThread...這個里面是什么啊

ArmyRunnable這個Runnable里面寫的是什么啊
