Examples of java.util.zip.ZipInputStream.available()

java.util.zip.ZipInputStream.available()
Returns 0 after EOF has reached for the current entry data, otherwise always return 1.
Programs should not count on this method to return the actual number of bytes that could be read without blocking. @return 1 before EOF and 0 after EOF has reached for current entry. @exception IOException if an I/O error occurs.

        // the fileName is found, return the InputStream.

          System.out.println("RAConfig.extractFromJAR : currEntry = " + currEntry);
