The program seems clearcut.

public class Messager implements Runnable
{
public static void main(String[] args)
{
new Thread(new Messager("wallace")).start(); //new thread object
//created and started
new Thread(new Messager("gromit")).start(); //same here
}
private String name;
public Messager(String name) //object Messager constructor
{
this.name=name; // setts arg name to instance variable
}
public void run() // the run method
{
message(1); //run the message(int n) method
message(2); //again by passing another parameter
}
private synchronized void message(int n) //thread lock
{
System.out.print(name + "-" + n + " "); //prints the thread name and the
//passed parameter
}
}
