Long compressedSize = zipEntry. ZipEntry zipEntry = (ZipEntry) enu.nextElement() ZipFile zipFile = new ZipFile( "test.zip") If it has a parent, the parent directory is created along with any other higher directories via the file.mkdirs() call.įollowing this, the ExtractZipContents class does some standard Java input stream/output stream code to read the contents of the current ZipEntry object and write the contents to the file that was created using the ZipEntry name. Given a Tar File as input it will untar the file in a the untar directory passed as the second parameter This utility will untar '.tar' files and '.tar.gz','tgz' files. If the name doesn't end with a slash, then we check to see if the file created from the current ZipEntry name has a parent file, which would be a directory. The 'continue' skips the rest of the code in the while loop and lets the while loop go to the next zip entry. If the name of the ZipEntry ends with a slash, it is a directory, and this directory gets created along with all other directories above it via file.mkdirs(). Another method is to use a GUI-based extractor, which. It displays the name, size, and compressed size of each ZipEntry object. To extract them, you can use the free command-line-based Java Archive Tool in the Java Development Kit. It then enumerates over the ZipEntry objects within the zip file. The directory tree(s) contained // within the TAR archive will be re-created rooted at this // directory. It creates a ZipFile object based on test.zip. CkTar tar new CkTar() int fileCount // Untar into c:/temp/untarDir. Please note that the tar archive may contain folders as well, case in which they need to be created on the local filesystem. So, for a file tar.gz, you need to first unzip it and after that untar it.Given a Tar File as input it will untar the file in a the untar directory passed as the second param. The ExtractZipContents class is shown below. Here are two methods: one that unzips a file and another one that untars it. This java.io API returns null when a dir is not a directory or for a. We can double-check this by examining the contents of test.zip with WinZip: The contents of the test.zip file are shown below. The test.zip file is the zip file that we will unzip, and ExtractZipContents is the Java class that will extract the contents of the zip file and write them to the file system. Create a simple ZIP File: not retain any directory path information about the files. This tutorial will utilize the following project. This tutorial will examine how to extract the contents of a zip file using the package and a little basic File/Stream Java S W code. In another tutorial, we saw how we could use the package to display the contents of a zip file.
