Reading and writing file

[FaisalBahadur]

Helo! I need a simple java code that ask the user to select a jar file by navigating through hard drive and then i want that selected file to store /write in a particular destination(ie my own folder)..Thanks

The JFileChooser class is useful for allowing a user to choose a file to open.

For reading from and writing to a file, the RandomAccessFile is useful.

ok ...JFilechooser will help me to just point to a file then is there a way to just copy that file to particular destination without reading or writing...ie i need a simplest way of copying that file to some other destination,,,

The easiest way is to simply copy the contents yourself.
Create a new File object at the target destination, open the new file object, write the contents of the old file into the new file, and then remove the old file.

copy that file to particular destination without reading or writing.

That sounds like magic: no reading or writing.
To copy a file, the source must be read and the new file written.

Some OSs have utilities to copy files. Perhaps you could execute one of them to do the copy.
