Exchange data exchange between multiple threads
Use exchange to interact with data between two threads. The threads must appear in pairs, otherwise the threads will always be in a waiting state, or set a timeout. The data interaction between multiple threads is random
final Exchanger<String> objectExchanger = new Exchanger<>();
new Thread(() -> {
try {
System.out.println("我有10块钱， 我去超市买苹果");
Object exchange = objectExchanger.exchange("10RMB");
System.out.println("买到了" + exchange.toString());
} catch (InterruptedException e) {
e.printStackTrace();
}
}).start();
new Thread(() -> {
try {
System.out.println("超市中有苹果！");
Object exchange = objectExchanger.exchange("苹果");
System.out.println("出售了苹果，收到" + exchange.toString());
} catch (InterruptedException e) {
e.printStackTrace();
}
}).start();
}
