Part II - Process synchronization Write a program that consists in 4 threads that must be executed in a specific order (see the graph). Task 1 Task 3 Task 2 Task 4 Task 3 cannot be started before EITHER Task 1 or Task 2 ends; Task 4 can be started only after Task 2 AND Task 3 end. [Note]: - We mean by Task I; a thread that prints \"TASK I COMPLETED\" on screen. - Use SEMAPHORES to solve this problem

Step 1
First, we need to create a Semaphore object to control the execution order of the threads. We will initialize it with 0 permits, so that the first thread will be blocked until it is released. Semaphore semaphore = new Semaphore(0); Show more…

A small firm builds two types of products. Type A requires 20 minutes on threading machine, 10 minutes on slotting machine and 7.5 minutes of craftsman time. Type B requires 10 minutes on threading machine, 20 minutes on slotting machine and 30 minutes of craftsman time. Each day there are 200 minutes of threading machine time, 120 minutes of slotting machine time and 150 minutes of craftsman time available. The profit on each type A product is $5 and on each type B product is $12. To maximize profit, please: 1. Formulate the appropriate linear programming problem. 2. Use graphical solution to solve it, please mark corner points clearly. 3. You can draw the graph by hand, take a picture of your solution
