(Synchronized threads) Write a program that launches 1000 threads. Each thread adds a random integer (ranging from 1 to 3, inclusive) to a variable sum that is initially 0. You need to pass sum by reference to each thread. In order to pass it by reference, define an Integer wrapper object to hold sum. Run the program with and without synchronization to see its effect.

Main(){
ExecutorService e=Executors.newFixedThreadPool(1000);
final Sum s = new Sum();
for(int i=0;i<1000;i++){
e.execute(s);
}
e.shutdown();
while(!e.isTerminated()){
}
System.out.println(sum);
}
public static void main(String[]args){
new Main();

in main() we first declare a variable called mythread, which has a type of pthread_t. this is essentially an id for a thread. next, the if statement creates a thread associated with mythread. the call pthread_create() returns zero on success and a nonzero value on failure. the third argument of pthread_create() is the name of a function that the new thread will execute when it starts. when this thread_function() returns, the thread terminates. meanwhile, the main program itself defines a thread, so that there are two threads executing. the pthread_join function enables the main thread to wait until the new thread completes.
