```
public ZipEntry(String name)
```
    Creates a new zip entry with the specified name.
    
    Parameters:
    
    name - The entry name
    
    Throws:
    
    NullPointerException - if the entry name is null

  - setTime
```
public void setTime(long time)
```
    Sets the last modification time of the entry.
    If the entry is output to a ZIP file or ZIP file formatted output stream the last modification time set by this method will be stored into the date and time fields of the zip file entry and encoded in standard MS-DOS date and time format.
