Exchanger
很有意思的一个小工具，能直接等到两个线程都执行到exchange中然后交换数据。
public class UseExchanger {
public static void main(String[] args) {
Exchanger<Human> exchanger = new Exchanger<>();
new Thread(() -> {
try {
Thread.sleep(10000);
Human feng = new Human("feng wen", 26, "男");
Human changed = exchanger.exchange(feng);
System.out.println(Thread.currentThread().getName() + ":" + changed);
} catch (InterruptedException e) {
e.printStackTrace();
}
}, "Thread-Feng").start();
new Thread(() -> {
try {
Thread.sleep(2000);
Human yi = new Human("lin yi", 25, "女");
Human changed = exchanger.exchange(yi);
System.out.println(Thread.currentThread().getName() + ":" + changed);
} catch (InterruptedException e) {
e.printStackTrace();
}
}, "Thread-Yi").start();
}
}
class Human {
private String name;
private int age;
private String gender;
public Human(String name, int age, String gender) {
this.name = name;
this.age = age;
this.gender = gender;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public int getAge() {
return age;
}
public void setAge(int age) {
this.age = age;
}
public String getGender() {
return gender;
}
public void setGender(String gender) {
this.gender = gender;
}
@Override
public String toString() {
return "Human{" +
"name='" + name + '\'' +
", age=" + age +
", gender='" + gender + '\'' +
'}';
}
}
