Threads and Arrays

[YASIN786]

hi ol

my name is yasin and am currently working on a java task for a friend.

the scenario is:
there are two threads thr1 and thr2 and one array arr1 with a capacity of 100.
the array is populated with random numbers in the range of 1-100.
the objective of the task is to find all the numbers in the array arr1 which are in the range of 70-80 using the thread thr1 and to send these numbers to the second thread thr2.

Any ideas/advice will highly be appreciated.

thanks.

So the array 'belongs' to thr1; this thread sends particular numbers to thr2. This makes
thr1 a 'producer' and 'thr2' a consumer where the number is the 'shared resource'.
There should be a 'semaphore' indicating that a number can be consumed or a new
number should be produced. Both threads wait on that condition; the consumer
delivers a new number and sets the condition; otherwise it waits.

The producer waits on the opposite of the condition (the previous number wasn't
consumed yet) and delivers a next number and resets the condition. Both threads
notify each other when they've done what they must do.

kind regards,
