thread

[snehasishmohanta@gmail.co]

i want to create two thread one thread will print odd number and another thread will print even number. but the number should be in a sequence like

1 2 3 4 5 6 7 8 9 10

help me.

First of all you should create 2 threads, either pass a runnable to either of them or use annonymous sub-classes of thread that overwrite their run() method.
Have them print numbers inside a for loop.

Then think of a good way to synchronize their actions, perhaps a lock, or an atomic counter. Choice is yours.

yea i already did that .but i am stuck in the next part means synchronization of method.please help me to write that code.


actually i wrote the below code.

package com.java.demo;


public class Practice1
{
public static void main(String [] args)
{
Thread t2=new MyThread1();
t2.start();
Thread t1=new MyThread();
t1.start();
}
}
class MyThread1 extends Thread
{
public void run()
{
for(int i=1;i<=10;i+=2)
{
System.out.println(i);
try {
Thread.sleep(500);
} catch (InterruptedException e) {
e.printStackTrace();
}
}
}
}

class MyThread extends Thread
{
public void run()
{
for(int j=2;j<=10;j+=2)
{
System.out.println(j);
try {
Thread.sleep(500);
} catch (InterruptedException e)
{
e.printStackTrace();
}
}
}
}

but i am getting o/p-

1
2
3
4
6
5
7
8
10
9

i want o/p as-

1
2
3
4
5
6
7
8
9
10

What methods for synchronization do you know and which do you want to use?

[snehasishmohanta@gmail.co]

if we write synchronized before any method it will get synchronized. but in this program what is the solution i am not getting.

[Cornix]

I meant other ways of synchronization, there is more then one.
Maybe google "consumer producer synchronization" and read up on some documentations and articles describing what it is.
