6. Project Title: The Sandwich Problem Project Description: There are four students sitting in a room: three juniors and one senior. Each of the juniors will make a sandwich and eat it. To make a sandwich requires bread, cheese, and sausage. Each junior has one of the three items, that is, one has bread, another has cheese and the third has sausage. The senior has infinite supply of all three items. The senior places two of the three items on the table, and the junior that has the third item, makes the sandwich. However, the other two juniors cannot make a sandwich because they do not have the third required item. Thus, a junior can make a sandwich only when all the three items are available to him. Implement a synchronization method to solve the problem. 6. Project Title: The Sandwich Problem Project Description: There are four students sitting in a room: three juniors and one senior.
