如何在JAVA中获取文件中最后一次写入的位置？

import java.io.File;
import java.io.RandomAccessFile;

public class LastWritePosition {
    public static void main(String[] args) {
        File file = new File("path/to/file.txt");
        
        try (RandomAccessFile raf = new RandomAccessFile(file, "r")) {
            long fileLength = raf.length();
            raf.seek(fileLength);
            long lastWritePosition = raf.getFilePointer();
            
            System.out.println("Last write position: " + lastWritePosition);
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}
