Java Utililty Methods ZipEntry Read

ZipEntry getNextZipEntry(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);

String getSimpleName(ZipEntry entry)
get Simple Name

return getSimpleName(entry.getName());

File getZipEntry(File f, String nameToRead, String fileName)
Get an entry from the specified zip file

byte[] fileBytes = new byte[1024];
File fileOut = new File(fileName);
FileOutputStream outStream = null;
FileInputStream fileInputStream = null;
ZipInputStream zipInputStream = null;
OutputStream out = null;
ZipEntry temp;
try {
...

ZipEntry getZipEntry(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;
...

ZipEntry getZipEntry(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;
...

ZipEntry getZipEntry(String zipEntryName)
Returns ZipEntry which is usable in both Linux and Windows.

return new ZipEntry(zipEntryName.replace(File.separator, "/"));

Map getZipEntry(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()) {
...

ZipEntry getZipEntry(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;

ZipEntry getZipEntry(ZipFile zip, final String name)
get Zip Entry

final String lcasename = name.toLowerCase();
for (Enumeration<?> itr = zip.entries(); itr.hasMoreElements();) {
 final ZipEntry zipentry = (ZipEntry) itr.nextElement();
 if (zipentry.getName().toLowerCase().equals(lcasename)) {
 return zipentry;
return null;
...

ZipEntry getZipEntry(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();
 if (entryName.equals(lcasename)) {
 return zipentry;
return null;
