synchronization kid riding a swing n catching breath

[jodeen20]

Hi java gurus im a newbie in jave have a problem with my java synchronized methods.. the output should be like this

Alice: I want to ride the swing
Alice: I get to ride the swing for 5940 ms
Bob: I want to ride the swing
Charlie: I want to ride the swing
Alice: Im tired pausing for 4440 ms
Bob: I get to ride the swing for 4231 ms
Alice: I want to ride the swing
Bob: Im tired pausing for 6934 ms
Charlie: I get to ride the swing for 4204 ms
....

this is my code.. any help would be greatly appreciated. Thanks! :)

class MyRideSwing {
public void rideswing(String name) {
int mydelay = (int)(Math.random() * 5000);
System.out.println(name + ": want");
synchronized(this) {
System.out.println(name + ": I get to ride the swing for " + mydelay +" milleseconds");
try {
Thread.sleep(mydelay);
}catch (InterruptedException e){}
this.breathe(name);
}
}
public void breathe(String name) {
int mydelay = (int)(Math.random() * 5000);
System.out.println(name + ": tired" + mydelay +" milleseconds");
try {
Thread.sleep(mydelay);
}catch (InterruptedException e){}
}
}

class Kid extends Thread {
String name;
MyRideSwing p;
Kid(String name, MyRideSwing p) {
this.name = name; this.p = p;
}
public void run() {
for (int ctr=0; ctr < 500; ctr++) {
p.rideswing(name);
}
}

}

class RideASwing {
public static void main(String args[]){
MyRideSwing p = new MyRideSwing();
Kid k1 = new Kid("Alice",p);
Kid k2 = new Kid("Bob",p);
Kid k3 = new Kid("Charlie",p);
k1.start();
k2.start();
k3.start();
}
}

hello
when u r create more than one thread and start it ,you cannot say that threads run in specific manner,JVM run thread with thread priority and scheduling algorithm which platform dependant.
Hence order in which u want to print output is not possible

Hi,
Even i do go with the solution provided threads cant be managed to work in a specific order you want. Plz try some other alternative method for printing in a specific order you want other than threads.
