线程问题"调用线程无法访问此对象,因为不同的线程拥有它".有解决方案吗

public synchronized void methodName() {
    // 访问共享资源的代码
}

public void methodName() {
    synchronized (this) {
        // 访问共享资源的代码
    }
}

import java.util.concurrent.locks.ReentrantLock;

public class MyClass {
    private final ReentrantLock lock = new ReentrantLock();

    public void methodName() {
        lock.lock();
        try {
            // 访问共享资源的代码
        } finally {
            lock.unlock();
        }
    }
}

import java.util.concurrent.Semaphore;

public class MyClass {
    private final Semaphore semaphore = new Semaphore(1);

    public void methodName() {
        try {
            semaphore.acquire();
            // 访问共享资源的代码
        } finally {
            semaphore.release();
        }
    }
}

import java.util.concurrent.CountDownLatch;

public class MyClass {
    private final CountDownLatch latch = new CountDownLatch(1);

    public void methodName() {
        try {
            // 访问共享资源的代码
        } finally {
            latch.countDown();
        }
    }
}
