Stage的run方法里有armyOfFarmer.join();這句。這句的意思是說農(nóng)民的run方法執(zhí)行完了才能往armyOfFarmer.join();這句代碼之后運(yùn)行。但你看看你的ArmyRunnable的run方法里，while?(keepRunning)的keepRuning一直是true，while循環(huán)沒有被終止。所以發(fā)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(huì)發(fā)生死鎖了。
下面是我修改之后的代碼
