Java代码

 

//      BufferedReader in = null;
//      BufferedWriter out = null;
Reader in = null;
Writer out = null;
try {
//          in = new BufferedReader(new FileReader(src));
//          in = new BufferedReader(new InputStreamReader(new FileInputStream(src)));
//          out = new BufferedWriter(new FileWriter(new File(dir， src.getName())));
//          out = new BufferedWriter(new OutputStreamWriter(new FileOutputStream(new File(dir， src.getName()))));
in = new FileReader(src);
out = new FileWriter(new File(dir， src.getName()));
System.out.println("正在拷贝文件(" + src + ")到目录("+dir+")下");
char[] buffer = new char[1024];
int len = 0;
while((len = in.read(buffer)) != -1) {
out.write(buffer， 0， len);
out.flush();
}
return true;
} catch (Exception e) {
return false;
} finally {
closeIO(in， out);
}
