How to access static variable from a Thread class

Question

Kindly help me.......
here's the code.....
class Thread1 extends Thread
int j=0;
myClass2 mc = new myClass2();
     public void run()
          for( int a=0;a<6;a++)
                    {try
                         { Thread.sleep(5000);
                         catch(Exception e){System.out.println("Interrupted Exception");}
                         j++;
mc.change1(i);
} System.out.println("Thread1 executes "+j+" times");
class Thread2 extends Thread
int k=0;
     myClass2 mc1 = new myClass2();
     public void run()
          for( int a=0;a<6;a++)
                    {try
                         { Thread.sleep(5000);
                         catch(Exception e){System.out.println("Interrupted Exception");}
                         k++;
mc1.change2(i);
}System.out.println("Thread2 executes "+k+" times");
class myClass2
static int i=5;
public synchronized void change1(int s)
s=6;
System.out.println("New value of i:"+s);
public synchronized void change2(int s)
s=7;
System.out.println("New value of i:"+s);
     public static void main(String args[])
Thread1 b1 = new Thread1();
Thread2 b2 = new Thread2();
     b1.start();
b2.start();
I am unable to pass the variable i in my method call in Thread1: mc.change1(i); and similarly in Thread2:mc.change2(i);

You can declare your i variable in myClass2 as public static and then simply call there
    mc.change1( myClass2.i ) ;
