Subtract element from Array.

[Mike2020]

Hi All,

I created an Array.

Thread[] ThreadArray = New Thread[5];

for(int i; i <5; i++)
{
ThreaArray = new TryThread(TName, "Work ", 1000L);
ThreadArray.start();
}

now, I want the Main Thread to Check whether the Child Thread is alive or not, if it die. then Stop check it. That mean I want to remove that thread element out of the array.
How can I do that?

for(int i; i < ThreadArray.length; i++)
{
if (ThreadArray.IsAlive() == false)
{ Remove Element from array; }

}

Thanks....

Mike

Arrays are immutable objects because you request a specific amount of memory in the heap to store your array and its elements ...

If you want an *array* that grows or shrinks, then use an ArrayList or Vector or something :

int numThreads = 5;
Vector v = new Vector();

for(int i = 0; i < numThreads; i++) {
   Thread t = new TryThread(TName, "Work ", 1000L);
   v.addElement(t);
   t.start();
}

for(int i = 0; i < v.size(); i++) {
   Thread t = (Thread)v.elementAt(i);
   if (t.IsAlive() == false) {
       al.remove(t);
       // decrement 'i' else you will screw the vector
       i--;
   }
}
