import java.io.File;
import java.io.IOException;

public class FileRenameExample {
    public static void main(String[] args) {
        File file = new File("path/to/file.txt");
        File newFile = new File("path/to/newfile.txt");

        boolean renamed = file.renameTo(newFile);
        if (renamed) {
            System.out.println("文件名已成功转换！");
        } else {
            System.out.println("转换文件名时出现错误！");
            try {
                throw new IOException("文件名转换错误");
            } catch (IOException e) {
                System.out.println("错误信息：" + e.getMessage());
            }
        }
