缓冲技术

11.17

今天练习的是缓冲技术的代码:

代码部分;

package lianxi;
import java.io.*;

public class bo
{
public static void main(String[] args) {
try {
byte[] data = new byte[1];

File srcFile = new File("D://c.txt");
File desFile = new File("D://d.txt");

BufferedInputStream bufferedInputStream =
new BufferedInputStream(
new FileInputStream(srcFile));
BufferedOutputStream bufferedOutputStream =
new BufferedOutputStream(
new FileOutputStream(desFile));

System.out.println("复制文件:" +
srcFile.length() + "字节");

while(bufferedInputStream.read(data) != -1) {
bufferedOutputStream.write(data);
}

// 将缓冲区中的数据全部写出
bufferedOutputStream.flush();

// 关闭流

bufferedInputStream.close();
bufferedOutputStream.close();

System.out.println("复制完成");
}
catch(IOException e) {
e.printStackTrace();
}
}
}

 运行结果:

 

 运行结果分析:

最后成功吧C文件里的内容复制到D文件。
