This is an example of how to extract a compressed zip file. Extracting a compressed zip file implies that you should:
- Create a FileInputStream by opening a connection to an actual file, the file named by the path name name in the file system.
- Create a new ZipInputStream.
- Create a new FileOutputStream using a path name to the file to write.
- Iterate over the ZipEntries of the ZipInputStream, using
getNextEntry()method of ZipInputStream. - Read from the ZipInputStream, using its
read(byte[] b, int off, int len)API method and write to the FileOutputStream withwrite(byte[] b, int off, int len)API method.
Let’s take a look at the code snippet that follows:
package com.javacodegeeks.snippets.core;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.OutputStream;
import java.util.zip.ZipEntry;
import java.util.zip.ZipInputStream;
public class ExtractZipFile {
//Zipped file path e.g. C:/Users/nikos7/comperssed.zio
private static final String zippedFilePath="<ZIPPED FILE PATH>";
private static final String outputFilePath="<OUTPUT FILE PATH>";
public static void main(String[] args) throws Exception {
ZipInputStream inputStream = new ZipInputStream(new FileInputStream(zippedFilePath));
OutputStream outputStream = new FileOutputStream(outputFilePath);
byte[] buf = new byte[1024];
int read;
ZipEntry zipEntry;
if ((zipEntry = inputStream.getNextEntry()) != null) {
while ((read = inputStream.read(buf)) > 0) {
outputStream.write(buf, 0, read);
}
}
outputStream.close();
inputStream.close();
}
}
This was an example of how to extract a compressed zip file in Java.
