Zip File Creation In Java Example

Java Code:


import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.IOException;
import java.util.zip.ZipEntry;
import java.util.zip.ZipOutputStream;

public class JavaZipFileExample {
	public static void main(String[] args) {
		byte[] buffer = new byte[1024];

		try {

			FileOutputStream fos = new FileOutputStream("C:\\MyFile.zip");
			ZipOutputStream zos = new ZipOutputStream(fos);
			ZipEntry ze = new ZipEntry("scan.log");
			zos.putNextEntry(ze);
			FileInputStream in = new FileInputStream("C:\\scan.log");

			int len;
			while ((len = in.read(buffer)) > 0) {
				zos.write(buffer, 0, len);
			}

			in.close();
			zos.closeEntry();

			// remember close it
			zos.close();

			System.out.println("Done");

		} catch (IOException ex) {
			ex.printStackTrace();
		}
	}
}

import java.io.FileInputStream;

import java.io.FileOutputStream;

import java.io.IOException;

import java.util.zip.ZipEntry;

import java.util.zip.ZipOutputStream;

public class JavaZipFileExample {

public static void main(String[] args) {

try {

FileOutputStream fos = new FileOutputStream("C:\\MyFile.zip");

ZipOutputStream zos = new ZipOutputStream(fos);

ZipEntry ze = new ZipEntry("scan.log");

zos.putNextEntry(ze);

FileInputStream in = new FileInputStream("C:\\scan.log");

int len;

while ((len = in.read(buffer)) > 0) {

zos.write(buffer, 0, len);

}

in.close();

zos.closeEntry();

// remember close it

zos.close();

System.out.println("Done");

} catch (IOException ex) {

ex.printStackTrace();

}

Java comes with java.util.zip library to perform data compression in ZIP format.

FileOutputStream to write to the file with the specified name, that is the zipFile.
