When a thread enters an synchronized method of an object, can other threads enter other methods of this object? __java Multithreading

The Synchronized method of an object cannot be entered, but its other synchronized methods are accessible.

Let's take a look at an example:

Package dhp.test1;

public class TT implements Runnable {
     int b = m;
     Public synchronized void M1 () {
            b = 10000;
            try {
                Thread. Sleep (5000);
                System. OUT.PRINTLN ("m1----b=" + b);
           } catch (Interruptedexception e) {
                e.printstacktrace ();
           }
     }
     public void m2 () {
           System. Out.println ("m2=====" + b);
     }
     @Override public
     Void Run () {
           m1 ();
     }
     public static void Main (string[] args) {
           tt tt = new TT ();
           Thread t = new thread (TT);
           T.start ();
            try {
                Thread. Sleep (1000);
           } catch (Interruptedexception e) {
                e.printstacktrace ();
           }
           TT.M2 ();
     }
