Examine the SharedData Class Shown Below

question 64

Multiple Choice

Examine the SharedData class shown below. Suppose two threads are created so that each has access to the same SharedData object. Thread one calls setSharedData eight times with values 1...8 respectively, sleeping for 30 milliseconds between calls. Thread two calls getSharedData eight times, also sleeping for 30 milliseconds between calls. What is one reason why thread two may not receive 7 and 8 on its two final calls to getSharedData? public class SharedData
{
Private int value;
Public void setSharedData(int n)
{
Value = n;
}
Public int getSharedData()
{
Return value;
}
}
