How to check the value of "The Interrupt Status Flag"?

Question

Hi, thank you for reading this post!
Invoking Thread.interrupt() sets the value of the Interrupt Status Flag.
Just wondering if there is a Java method to check the value of this flag? Or is using isInterrupted() or interrupted() the only way to check?

Thank you in advance for your help!

Below is the full code. As soon as the Thread.sleep() is taken out in main(), the interrupt is detected in the child thread. But if the sleep() stays, then the child thread goes into an infinite loop. It's not detected the interrupt.
//ParentInterruptChildThreadCatchedDemo.java
//Program function: This program demonstrates the parent thread (main()) interrupting a child thread (thread1).
//Threaded class
class TryThread extends Thread {
     //fields
     private String threadname;
     private long aWhile;
     //Constructor
     public TryThread(String tname, long delay) {
          threadname = tname;
          aWhile = delay;
     //run() method
     public void run() {
          while(!Thread.interrupted()) {
               //Do work
          try {
               System.out.println(Thread.currentThread().getName() + " was just interrupted!");
               throw new InterruptedException();
          } catch(InterruptedException e) {
               //System.exit(1);
               return;
public class ParentInterruptChildThreadCatchedDemo {
     public static void main(String[] args) {
          Thread thread1 = new TryThread("thread1", 2000L);
          thread1.start();
          try {
               System.out.println("main() goes to sleep for 10 second.");
               Thread.sleep(10000);
               System.out.println("Statement after main() sleep().");
          } catch(InterruptedException e) {
                e.printStackTrace();
             //Interrupt thread1
              int interruptFlag = 5;
              for(int i=0; i<11; i++) {
                   if(i == interruptFlag) {
                        System.out.println("Condition met, going to interrupt thread1 ...");
                        thread1.interrupt();
                        System.out.println("Thread1 interrupted!");
              System.out.println("Ending main()");
/*Output:
main() goes to sleep for 10 second.
Statement after main() sleep().
Condition met, going to interrupt thread1 ...
Thread1 interrupted!
Ending main()
INFINITION LOOP
