my program doesn't work correctly because this exception

while(count<sharedBetweenThreads.size()){

                for (int i = 0; (i < ourThreads.length)

                        && count < sharedBetweenThreads.size(); i++) {

                    if (ourThreads[i].isAlive() == false) {

                       

                        ourThreads[i].start();


                    }

                }

if the length of an array of threads(ourthreads) equal 2.
the two threads start and then the program check the while condition and if it's true
he check if ourThreads[i].isAlive() == false and then the thread must start
but unfouretantly ,it's throw this exception

please how can I solve this problem

You can never start a Thread twice.
A thread-instance can only run once, then it's dead.

You need to create a new Thread and start that.
Usually you want to use the Runnable for something like this.

public class YourClass implements Runnable {....}

// To use it;
...
Thread t = new Thread(new YourClass());
t.start();
...

You just start the threads once and let them run.
