Determining If the Current Thread Is Holding a Synchronized Lock

     

public class Main {
  public static void main(String[] argv) throws Exception {
    
  }
  public synchronized void myMethod() {
    Object o = new Object();

    System.out.println(Thread.holdsLock(o));
    synchronized (o) {
      System.out.println(Thread.holdsLock(o));
    }
    System.out.println(Thread.holdsLock(this));
  }
}
