用java将C盘hello.txt文件写入D盘，文件名为newHello.txt

以下是Java代码实现：

import java.io.*;

public class CopyFileExample {
   public static void main(String[] args) {
      FileInputStream inputStream = null;
      FileOutputStream outputStream = null;

      try {
         // 1. 创建输入流和输出流对象
         File inputFile = new File("C:\\hello.txt");
         File outputFile = new File("D:\\newHello.txt");
         inputStream = new FileInputStream(inputFile);
         outputStream = new FileOutputStream(outputFile);

         // 2. 读取输入流并写入输出流
         byte[] buffer = new byte[1024];
         int length;
         while ((length = inputStream.read(buffer)) > 0) {
            outputStream.write(buffer, 0, length);
         }

         // 3. 关闭输入流和输出流
         inputStream.close();
         outputStream.close();

         System.out.println("文件复制成功！");
      } catch (IOException e
