title: Decompressing a file like 7zip with Java
body: <p>I need to open a compresed file (zml, i don't couldn't find information about that extension) like 7zip does it with java.</p>
  
  <p>I have a zml file, if I open it with 7zip it asks me for the password, then I put the password and can open the file.</p>
  
  <p>I need to do the same with java, could anyone give me an advice for this?</p>
  
  <p>Best regards.</p>
