simple multi threaded java code

i have a redis atomic integer increment function that I want to call simultaneously multiple time as many times as I want (i just change value of integer and it will call the function that many times) the code i have now will call the function once I will repeat again, the basic idea is create a thread class that call the function ONCE. and run x number of threads on that class when I choose a value for number of threads and run the program I want the print out to be something like this. number of threads: x duration: x number of unique numbers: x the number of threads and number of unique numbers should be equal (each thread is executing an increment function) so if i choose 1000 threads then the threads shouldve produced you must have experience with redis and have a local cluster to run this on. this is URGENT. thank you!
