can we run a run() method with out using a start() method in a program?
public class A extends Thread
{
public void run()
{
System.out.println(" i will execute any way");
}
public static void main(string args[])
{
A a=new A();
a.run(); // no start method
}
}
public class A extends Thread
{
public void run()
{
System.out.println(" i will execute any way");
}
public static void main(string args[])
{
A a=new A();
a.run(); // no start method
}
}

Yes, but it won't work the way you expect it to work.
Calling the run() method directly would be like calling a normal method. No thread of execution is created, no concurrency. On the other hand, calling the start method spawns a new thread of execution which can execute concurrently with other threads by executing the run() method.
