Java.util.jar.JarEntry klasa u Javi

Ova se klasa koristi za predstavljanje unosa JAR datoteke. Konstruktori:
    JarEntry(JarEntry jesti) :Stvara novi JarEntry s poljima preuzetim iz navedenog JarEntry objekta. JarEntry(naziv niza):Stvara novi JarEntry za navedeni naziv unosa JAR datoteke. JarEntry(ZipEntry sa):Stvara novi JarEntry s poljima preuzetim iz navedenog ZipEntry objekta.
Metode:
    Atributi getAttributes() : Returns the Manifest Attributes for this entry or null if none. 
      Syntax :  public Attributes getAttributes() throws IOException   Returns:   the Manifest Attributes for this entry or null if none
    Certifikat[] getCertificates() : Returns the Certificate objects for this entry or null if none. 
      Syntax :  public Certificate[] getCertificates()   Returns:   the Certificate objects for this entry or null if none.
    CodeSigner[] getCodeSigners() : Returns the CodeSigner objects for this entry or null if none. 
      Syntax :  public CodeSigner[] getCodeSigners()   Returns:   the CodeSigner objects for this entry or null if none.
