你的thread創(chuàng)建了,但沒(méi)有啟動(dòng),要通過(guò)start啟動(dòng)
把main函數(shù)改成下面這樣就可以了

        System.out.println("enum = " + JobType.START);
        final NetSchedulerTest myt2 = new NetSchedulerTest();

            public void run() { myt2.CurrentThread01();  }
        }, "CurrentThread01"  ).start();
        new Thread(  new Runnable() {
            public void run() { myt2.CurrentThread02();   }
        }, "CurrentThread02"  ).start();

    }
