Java Replication Folder

File.separator Slash uses this parameter instead to solve Java porting to its other platform compatibility issues


String Fsr=string.format ("D:%sceshi", file.separator);//folders that need to be copied do not include Ceshi
String Tsr=string.format ("D:%sdownloads", file.separator);//folder to be copied to
File F=new file (FSR);
File T=new file (TSR);
if (F.exists () &&f.isdirectory ())
{

File[] Filelist=f.listfiles ();
int fcout=filelist.length;
for (int i=0;i<fcout;i++)
{
Filechannelcopy (filelist[i],t);
}


}




Ways to copy Folders


public void Filechannelcopy (file s, file T) {


if (S.isdirectory ())
{
File Nf=new file (String.Format (T.getpath () +file.separator+s.getname ()));
if (!nf.exists ())
{
Nf.mkdir ();
}

File[] Filelist=s.listfiles ();
for (File fi:filelist)
{
Nf=new File (String.Format (Nf.getpath ()));
Filechannelcopy (FI,NF);
}
}
Else
{
FileInputStream fi = null;


FileOutputStream fo = null;


FileChannel in = null;


FileChannel out = null;


try {
T=new File (String.Format (T.getpath () +file.separator+s.getname ()));
fi = new FileInputStream (s);


fo = new FileOutputStream (t);


in = Fi.getchannel ();//get corresponding file channel


out = Fo.getchannel ();//get the corresponding file channel


In.transferto (0, In.size (), out);//Connect two channels and read from the in channel and write to the out channel


} catch (IOException e) {


E.printstacktrace ();


} finally {


try {


Fi.close ();


In.close ();


Fo.close ();


Out.close ();


} catch (IOException e) {


E.printstacktrace ();


}


}
}
