Method

ZipEntrygetNextZipEntry(ZipInputStream in)
Reads the next ZIP file entry from the ZipInputStream and positions the stream at the beginning of the entry data. 
try {
    return in.getNextEntry();
} catch (Exception ex) {
    throw new RuntimeException("Failed to get next entry in ZIP-file", ex);
StringgetSimpleName(ZipEntry entry)
get Simple Name 
return getSimpleName(entry.getName());

Get an entry from the specified zip file 
byte[] fileBytes = new byte[1024];
File fileOut = new File(fileName);
FileOutputStream outStream = null;
FileInputStream fileInputStream = null;

ZipEntrygetZipEntry(final ZipFile zipFile, final CharSequence zippedName)
A sane way of retrieving an entry from a ZipFile based on its /-delimited path name. 
Enumeration<? extends ZipEntry> entries = zipFile.entries();
while (entries.hasMoreElements()) {
    ZipEntry entry = entries.nextElement();
    if (PATH_SEPARATORS.matcher(entry.getName()).replaceAll("/")
            .equals(PATH_SEPARATORS.matcher(zippedName).replaceAll("/")))
        return entry;
return null;
...
ZipEntrygetZipEntry(String name, ZipFile zipFile)
get Zip Entry 
Enumeration<? extends ZipEntry> entries = zipFile.entries();
while (entries.hasMoreElements()) {
    ZipEntry entry = entries.nextElement();
    if (entry.getName().endsWith(name)) {
        return entry;
return null;
...
ZipEntrygetZipEntry(String zipEntryName)
Returns ZipEntry which is usable in both Linux and Windows. 
return new ZipEntry(zipEntryName.replace(File.separator, "/"));
MapgetZipEntry(String zipFileLoc)
Get File entries and size from a zip file... 
ZipInputStream zipIn = null;
Map<String, Long> entryMap = null;
try {
    zipIn = new ZipInputStream(new FileInputStream(zipFileLoc));
    ZipEntry entry = zipIn.getNextEntry();
    entryMap = new HashMap<String, Long>();
    while (entry != null) {
        if (!entry.isDirectory()) {
...
ZipEntrygetZipEntry(ZipFile jarFile, String path)
get Zip Entry 
Enumeration<? extends ZipEntry> entries = jarFile.entries();
String expected = normalizePath(path);
while (entries.hasMoreElements()) {
    ZipEntry entry = entries.nextElement();
    String test = normalizePath(entry.getName());
    if (expected.equals(test)) {
        return entry;
return null;

get Zip Entry 
final String lcasename = name.toLowerCase();
for (Enumeration<?> itr = zip.entries(); itr.hasMoreElements();) {

ZipEntrygetZipEntry(ZipFile zip, String name)
get Zip Entry 
String lcasename = name.toLowerCase();
for (Enumeration<? extends ZipEntry> itr = zip.entries(); itr.hasMoreElements();) {
    ZipEntry zipentry = itr.nextElement();
    String entryName = zipentry.getName().toLowerCase();
