通知唤醒其他线程时，感觉像锁死了一样

这个代码在通知唤醒时怎么感觉像是锁死了
输出语句就一句


public class Test5 {
    public static void main(String[] args) {
        Data2 data = new Data2();
        new Thread(() -> {
            for (int i = 0; i < 10; i++) {
                try {
                    data.printA();
                } catch (InterruptedException e) {
                    e.printStackTrace();
                }
            }

        }, "A").start();

        new Thread(() -> {
            for (int i = 0; i < 10; i++) {
                try {
                    data.printB();
                } catch (InterruptedException e) {
                    e.printStackTrace();
                }
            }

        }, "B").start();
        new Thread(() -> {
            for (int i = 0; i < 10; i++) {
                try {
                    data.printC();
                } catch (InterruptedException e) {
                    e.printStackTrace();
                }
            }

        }, "C").start();
        new Thread(() -> {
            for (int i = 0; i < 10; i++) {
                try {
                    data.printD();
                } catch (InterruptedException e) {
                    e.printStackTrace();
                }
            }

        }, "D").start();

    }


}

        }

        finally {

        }
    }
}

await改为wait试试
