Classe Java.util.zip.ZipInputStream en Java

Cette classe implémente un filtre de flux d'entrée pour lire les fichiers au format de fichier ZIP. Inclut la prise en charge des entrées compressées et non compressées. Constructeurs :
    ZipInputStream(InputStream dans) :Crée un nouveau flux d'entrée ZIP. ZipInputStream(InputStream dans le jeu de caractères Charset) :Crée un nouveau flux d'entrée ZIP
Méthodes :
    int disponible() : Returns 0 after EOF has reached for the current entry data otherwise always return . Programs should not count on this method to return the actual number of bytes that could be read without blocking.
      Syntax :  public int available() throws IOException   Overrides:   available in class InflaterInputStream   Returns:   1 before EOF and 0 after EOF has reached for current entry. Programs should not count on this method to return the actual number of bytes that could be read without blocking.   Throws:   IOException 
    void close() : Closes this input stream and releases any system resources associated with the stream.
      Syntax :  public void close() throws IOException   Overrides:   close in class InflaterInputStream   Throws:   IOException
    void closeEntry() : Closes the current ZIP entry and positions the stream for reading the next entry.
      Syntax :  public void closeEntry() throws IOException   Throws:   ZipException IOException 
    protected ZipEntry createZipEntry(String name) : Creates a new ZipEntry object for the specified entry name.
      Syntax :  protected ZipEntry createZipEntry(String name)   Parameters:   name - the ZIP file entry name   Returns:   the ZipEntry just created
    ZipEntrygetNextEntry() : Reads the next ZIP file entry and positions the stream at the beginning of the entry data.
      Syntax :  public ZipEntry getNextEntry() throws IOException   Returns:   the next ZIP file entry or null if there are no more entries   Throws:   ZipException IOException 
    int read(byte[] b int off int len) : Reads from the current ZIP entry into an array of bytes. If len is not zero the method blocks until some input is available; otherwise no bytes are read and 0 is returned.
      Syntax :  public int read(byte[] b int off int len) throws IOException   Parameters:   b - the buffer into which the data is read off - the start offset in the destination array b len - the maximum number of bytes read   Returns:   the actual number of bytes read or -1 if the end of the entry is reached   Throws:   NullPointerException IndexOutOfBoundsException ZipException IOException
    saut long(long n) : Skips specified number of bytes in the current ZIP entry.
      Syntax :  public long skip(long n) throws IOException   Parameters:   n - the number of bytes to skip   Returns:   the actual number of bytes skipped   Throws:   ZipException IOException IllegalArgumentException
