Java Problem : Consider a factory for cookies that has four production lines $(1.\mathrm{.}4)$ with different products.

Each of the four lines produces a certain flavor cookie. Each one has a certain ingredient in stock as shown below:

line$1$: flour, line$2$: sugar, leine$3$: butter, line$4$: eggs,

The recipe for each line needs to have all four ingredients.

Therefore, each line needs three more ingredients to produce the different types of cookies in addition to their stock ingredient.

As an example, line$1$ has flour but it needs the ingredients: sugar, butter, and eggs. For line$2$ that needs to get flour, butter and eggs. The same goes for line $3$ and $4.$

The central line of the factory can provide randomly these ingredients as needed and notifies the line who needs these ingredients. When the line gets the ingredients produces the cookies and wait for the next ingredients to get from the central line.

Prepare a program that simulates this system using threads $($semaphores$).$
