Do u know how to write a few line of codes to create folder?

Question

hi all, I just need a few line of codes to create a folder in my directory. Can someone just write a few lines of codes to create a folder?Thanks!
This is my unzip codes and I need to put these few lines of codes in the "/* */" part. If I didn't create the folder (using codes)then it would not be unzipped.
import java.io.*;
import java.util.*;
import java.util.zip.*;
public class Unzip {
  public static final void copyInputStream(InputStream in, OutputStream out)
  throws IOException
    byte[] buffer = new byte[1024];
    int len;
    while((len = in.read(buffer)) >= 0)
      out.write(buffer, 0, len);
    in.close();
    out.close();
  public static final void main(String[] args) {
    Enumeration entries;
    ZipFile zipFile;
    try {
      zipFile = new ZipFile("C:\\Temp\\FolderZiper.zip");
      entries = zipFile.entries();
      while(entries.hasMoreElements()) {
        ZipEntry entry = (ZipEntry)entries.nextElement();
/*need to have the few lines of codes here*/
        if(entry.isDirectory()) {
          // Assume directories are stored parents first then children.
          System.err.println("Extracting directory: " + entry.getName());
          // This is not robust, just for demonstration purposes.
          (new File(entry.getName())).mkdir();
          continue;
        System.err.println("Extracting file: " + entry.getName());
        copyInputStream(zipFile.getInputStream(entry),
           new BufferedOutputStream(new FileOutputStream(new File("c:\\temp\\unzipping\\"+entry.getName()))));
      zipFile.close();
    } catch (IOException ioe) {
      System.err.println("Unhandled exception:");
      ioe.printStackTrace();
      return;
}

Answer 1

Given a file, you can create its parent directory like this:
File outFile = new File("c:\\temp\\unzipping\\"+entry.getName())
File parentDir = outFile.getParentFile();
if (!parentDir.exists()){
  parentDir.makeDirs();
}Not too hard is it?
