close

public static void close(JarFile thing)

close

public static void close(ZipFile thing)

isJarFile

public static boolean isJarFile(File file)
                         throws IOException

Determine whether a file is a JAR File. Note: Jar file is a zip file with an *optional* META-INF directory. Therefore, there is no reliable way to check if a file is a Jar file. So this functions returns the same as calling isZipFile(File).

Throws:

IOException

isZipFile

public static boolean isZipFile(File file)
                         throws IOException

Determine whether a file is a ZIP File.

Throws:

IOException
