I am having problems understanding the concept of thread and I been ask to write two single programs using multithread. They do not have to be difficult just a basic program that shows the main idea of multithread and not asking for my homework but I been searching and looking at many sites and still don get it. I know the fact that uses different classes and each thread run by itself a single process, that putting then together create a complete system.
This is what understood so far:
Class NewThread extends Thread
String name; // declaration of variables
NewThread (string threadname0
Name = threadname;
t = new Thread (this, name); // what it’s the purpose of having this here
system.out.println(“New Thread: “ + t);
t.start ( )
Public void run ( )
For (int i=5; i>0; i--)
System.out.println (name + “:” + i);
It’s a valid code for a multithread code or its missing more stuff
No you will get a null pointer exception since the t variable does not contain a Thread object.
Try running the following code to see that 2 threads are indeed executing. Rerun it a few times and notice
