??? //1，線程有四種狀態(tài)，新建，運行，中斷，死亡
??? //2,引起中斷的原因：sleep,io阻塞，wait,cpu切換線程的時候線程進(jìn)入中斷狀態(tài)
??? //3,一個線程執(zhí)行完run方法，進(jìn)入死亡狀態(tài)， 該線程不能在調(diào)用start方法
??? //4,線程死亡了，isAlive方法返回的是false
??? //5,建立線程有兩種方法，繼承Thread類或者實現(xiàn)Runable接口
??? //6,setPriority();方法來設(shè)置優(yōu)先級，一共有十個優(yōu)先級別
??? //7,為了防止資源競爭產(chǎn)生的死鎖，主要是在寫數(shù)據(jù)的時候
??? //8,同步方法需要掛起線程，恢復(fù)掛起的線程的地方使用wait(),notify(),notifyAll()方法
??? //9，不合理
??? //10,interrupt()吵醒休眠的線程
