Write a java application using the concepts of multithreading for a flower

shop where flowers are delivered based on order.

The Airplane always needs to check with the Airport to see if it has an

available runway before it's able to take off or land. Simulate the above-

Write a simulation program for the fruit market. The farmer will be able to

produce different types of fruits (apple, orange, grape, and watermelon),

and put them in the market to sell. The market has limited capacity and

farmers have to stand in a queue if the capacity is exceeded to sell their

fruits. Consumers can come to the market any time and purchase their

desired fruits; and if the fruits they want to buy runs out, they are willing to

wait until the supply of that kind is ready. (Hint: implementing this market

will encounter the producer and consumer problem, and it probably needs

multiple buffers for different kinds of fruits).

Write a program which takes as input a huge array of numbers. This array is

split into n sub-arrays and n threads apply a bubble sort on each of the n

sub-arrays. Lastly, another thread merges the n sorted sub-arrays into one

with the same size as the original array. Of course, the resulting array

should be sorted.

Write a program called ReverseHello.java that creates a thread (let's call it

Thread 1). Thread 1 creates another thread (Thread 2); Thread 2 creates

Thread 3; and so on, up to Thread 50. Each thread should print "Hello from

Thread <num>!", but you should structure your program such that the

threads print their greetings in reverse order.
