复制文件,只用到了File及其相关的Stream类。
public static boolean copyFile(String src,String dest,boolean deleteIfExist){
File fileObj = new File(dest);
if(fileObj.exists()){
if(!deleteIfExist){
return false;
}
fileObj.delete();
}
InputStream inputStream = null;
FileOutputStream fileOutputStream = null;
try{
fileObj = new File(dest);
fileObj.createNewFile();
inputStream = new FileInputStream(src);
fileOutputStream = new FileOutputStream(dest);
byte[] buffer = new byte[1024 * 100];
int byteread = 0;
while ( (byteread = inputStream.read(buffer)) != -1) {
fileOutputStream.write(buffer,0,byteread);
}
}catch (Exception ex){
ex.printStackTrace();
}finally {
IOHelper.close(inputStream);
IOHelper.close(fileOutputStream);
}
return true;
}
