Java 如何将一个文件复制到另一个文件中呢？

下文将通过示例的方式讲述，
 如何使用read和write 方法--将文件内容复制到另一个文件中，如下例所示:

import java.io.*;

public class testClass{
   public static void main(String[] args) 
   throws Exception {
      BufferedWriter o= new BufferedWriter
      (new FileWriter("java265.txt"));
      out1.write("java265是我最爱的Java教程网站\n");
      out1.close();

     //读取及写入操作
      InputStream in = new FileInputStream
      (new File("java265.txt"));
      OutputStream out = new FileOutputStream
      (new File("java265-2.txt"));
      byte[] buf = new byte[1024];
      int len;
      while ((len = in.read(buf)) > 0) {
         out.write(buf, 0, len);
      }
      in.close();
      out.close();
    
      //输出写入的效果
      BufferedReader in1 = new BufferedReader
      (new FileReader("java265-2.txt"));
      String str;
      while ((str = in1.readLine()) != null) {
         System.out.println(str);
      }
      in.close();
   }
}
