如果一个方法被锁住了，其他线程是否可以访问其他的没有被锁住的方法?

答案是可以的。

public class Runner implements Runnable {

int b = 100;

public synchronized void m1() throws Exception{
b = 1000;
Thread.sleep(5000);
System.out.println(“b = ” + b);
}

public void m2(){
System.out.println(b);
}

@Override
public void run() {
try {
m1();
} catch (Exception e) {
e.printStackTrace();
}
}

}

public class Test {

public static void main(String[] args) throws InterruptedException {

Runner r = new Runner();
Thread t = new Thread(r);
t.start();
Thread.sleep(1000);
r.m2();
}

}
