Calling run() without calling start() will effectively
execute run() in the current thread.then that time only one
thread it will be created.but n't achiving the mulithreading
concepts.

ex:-
class Sample extends Thread
{
Sample()
{
System.out.println("hai how are u");
}
public void run()
{
System.out.println("run method will be called");
}
}

public class ThreadExample
{
public static void main(String k[])
{
Sample s=new Sample();
s.run();
int k1=Sample.activeCount();

System.out.println(k1);
}
}

OUTPUT:
hai how are u
run method will be called
1
IN this program only one thread will be created.

start()--->
Calling start() will kick off a seperate thread,from your
current thread, which will then call run().

EX:-
class Sample extends Thread
{
Sample()
{
System.out.println("hai how are u");
}
public void run()
{
System.out.println("run method will be called");
}
}

public class ThreadExample
{
public static void main(String k[])
{
Sample s=new Sample();
s.start();
int k1=Sample.activeCount();

System.out.println(k1);
}
}
OUTPUT:
hai how are u
run method will be called
2
