多线程--力扣合集

ing

1279. 红绿灯路口

class TrafficLight {

    public TrafficLight() {

    }

    boolean road1IsGreen = true;

    public synchronized void carArrived(
            int carId,           // ID of the car
            int roadId,          // ID of the road the car travels on. Can be 1 (road A) or 2 (road B)
            int direction,       // Direction of the car
            Runnable turnGreen,  // Use turnGreen.run() to turn light to green on current road
            Runnable crossCar    // Use crossCar.run() to make car cross the intersection
    ) {
        if ((roadId == 1) != road1IsGreen) {
            turnGreen.run();
            road1IsGreen = !road1IsGreen;
        }
        crossCar.run();
    }
}

一个很简单的例子，来让我回顾一下基础线程操作。
