               int y;

          {

               x = a + 1;

          }

          void add(int a, int b)

          {

               x = a + 2;

          }

     class Overload_methods

     {

          public static void main(String args[])

          {

               overload obj = new overload();

               int a = 0;

               obj.add(6);

               System.out.println(obj.x);

          }

Run the Java program per the instructions in the "Peachy Assignments" description by having (and commenting out) the volatile declaration of the Req and Ack variables. This can make the execution effects of Req and Acq becoming vvisible across threads different (e.g. compilers can rearrange Req to be after Ack, as they are two independent and unrelated variables). Observe when the run without volatiles hangs (what input value did you supply)? 

Provide two answers:

* The input number that seemed to hang the execution 50% of the time or more

Write a 300-character (roughly) description of the purpose of this test and what you observed.
The notion of "happens before" is mentioned in my "Peachy Assignments". It basically says that if two instructions A and B come in a certain order, their executions must appear to be in that order also. This is achieved by slapping the "volatile" variable annotation.

Find fibonacci number 
example : 
fibo of 0 = 1
fibo of 1 = 1
fibo of 2 = fibo 0 + fibo 1 = 2
fibo of 3  = fibo 2 + fibo 1 = 3
fibo of 4 = fibo 3 + fibo 2 = 5
fibo of 5 = fibo 4 + fibo 3 = 8
write function
