把小孩醒来时的具体情况封装成事件类
Test.java
class WakenUpEvent{
private long time;
private String location;
private Child source;
public WakenUpEvent(long time, String location, Child source) {
super();
this.time = time;
this.location = location;
this.source = source;
}
public long getTime() {
return time;
}
public void setTime(long time) {
this.time = time;
}
public String getLocation() {
return location;
}
public void setLocation(String location) {
this.location = location;
}
public Child getSource() {
return source;
}
public void setSource(Child source) {
this.source = source;
}
}
class Child implements Runnable {
private Dad dad;
public Child(Dad dad) {
this.dad = dad;
}
public void wakeUp(){
dad.actionToWakenUp(new WakenUpEvent(System.currentTimeMillis(), "bed", this));
}
@Override
public void run() {
try {
Thread.sleep(3000);
} catch (Exception e) {
e.printStackTrace();
}
wakeUp();
}
}
class Dad {
public void actionToWakenUp(WakenUpEvent e) {
System.out.println(e.getTime());
System.out.println(e.getLocation());
System.out.println(e.getSource());
System.out.println("Fedd the child");
}
}
public class Test {
public static void main(String[] args) {
Dad d = new Dad();
Child c = new Child(d);
new Thread(c).start();
}
}
