Returns the pathname string of this abstract pathname's parent, or null if this pathname does not name a parent directory.

Usage

From source file:Main.java

/**
 *
 * @param fi/*w w  w  .  j  a  va 2 s  . co m*/
 * @param newName
 * @return
 */
public static File renameTo(File fi, String newName) {
    /* File.renameTo is a abstract file rename finction .
     * I override this function which return File but boolean.
     * To get the new File obj , you can separately rename the file you want to .
     * Example code:
     *
    File f = new File("D:\\abc.def") ;
    File tmp = renameTo(f,"a.a") ;
    renameTo(tmp,"b.b") ;
     */
    //It can rename the File to the same dir.
    String dest = fi.getParent();
    dest += "\\" + newName;
    //System.out.println("Rename To : "+dest) ;
    File newNameFile = new File(dest);
    fi.renameTo(newNameFile);
