BufferedOutputStream输出不完整？

Question

import java.io.BufferedInputStream;import java.io.BufferedOutputStream;import java.io.FileInputStream;import java.io.FileOutputStream;import java.io.IOException;public class Text{  public static void main(String[] args) throws IOException{    byte[] buf = new byte[1024];    FileInputStream input = new FileInputStream("D:\\Text\\Class\\Test.java");    BufferedInputStream bufferinput = new BufferedInputStream(input);    FileOutputStream output = new FileOutputStream("D:\\Text\\new_test.txt");    BufferedOutputStream bufferoutput = new BufferedOutputStream(output);    while( bufferinput.read(buf) != -1){      bufferoutput.write(buf,0,buf.length);    }    bufferoutput.flush();    bufferoutput.close();    output.close();    bufferinput.close();    input.close();    System.out.println("已结束！");  }}原文档是但输出只，读读到最后continue那，后面的分号及最后的几个}都没有，为什么？
