What will be the output of the program?

public class If2
{
static boolean b1, b2;
public static void main(String [] args)
{
int x = 0; if ( !b1 ) /* Line 7 */
{
if ( !b2 ) /* Line 9 */
{
b1 = true; x++;
if ( 5 > 6 ) { x++;
}
if ( !b1 ) x = x + 10;
else if ( b2 = true ) /* Line 19 */ x = x + 100;
else if ( b1 | b2 ) /* Line 21 */ x = x + 1000;
}
}
System.out.println(x);
}
}
