⚔️Java Thread

Class Features

• Simple and convenient class to start and terminate Java threads

• Any thread can issue kStop() to signal the KThread thread to terminate (with an optional Thread.interrupt())

• Pending thread termination can be checked with kMustTerminate()

• The kCleanup() method is automatically called before termination to allow resource cleanup

Example Main Thread

KThread kThread = new TestThread("Hello World");
KLog.info("Thread created and started");

K.waitSeconds(5);

kThread.kStop();
KLog.debug("Thread stopped");

Example Thread

public class TestThread extends KThread {

   private String gStartArgument = null;
	
   public TestThread(String argString) {
      gStartArgument = argString;
   }

   public void kStart() {
      KLog.info("Thread has started with argument " + gStartArgument);
		
      while (!kMustTerminate()) {
         KLog.info("Thread still running ...");
         K.waitSeconds(1);
      }
      KLog.info("Thread has terminated");
   }
	
   public synchronized void kCleanup() {
      KLog.info("Thread cleanup called");
   }
}
