Reentrant Lock
  Instance Code:
  public class ReGetLock implements Runnable {
    @Override
  ReGetLock rgl = new ReGetLock();
  public void run() {
    set();
    get();
  ReGetLock rgl = new ReGetLock();
  public synchronized void get() {
    set();
  ReGetLock rgl = new ReGetLock();
  public synchronized void set() {
    System.out.println(Thread.currentThread().getId());
    public static void main(String[] args) {
  ReGetLock rgl = new ReGetLock();
ReGetLock rgl = new ReGetLock();

new Thread(rgl).start();63Can the thread executing the code really enter the set method?

}63Can the thread executing the code really enter the set method?

because the thread rgl first called the get method, obtained the lock of the ReGetLock object, then when the thread rgl wants to enter the set method marked with the synchronized keyword, it will be blocked and wait indefinitely?;

Actually, no, in Java,
