Java program to create Zip files

In this post, I wanted to show how to create a zip file using a java program.
In this example, input to the program is test.html and out put would be outFile.zip which contains the given test.html.

The same program can be downloaded from here.

/*Program to create .zip files * Author: Anand Y */ import java.io.*; import java.util.zip.*; public class ZipFileExample { public static void main(String a[]) { try { //Input file whose content will be zipped String inputFile="test.html"; //Target zip file name String zipFile="outFile.zip"; //Create object to the target zip file ZipOutputStream out = new ZipOutputStream(new BufferedOutputStream( new FileOutputStream(zipFile))); //Stream to read the content from input file BufferedInputStream in = new BufferedInputStream( new FileInputStream(inputFile)); int count; byte[] data = new byte[1024]; //Create a file in the zip file to which the source content will be written out.putNextEntry(new ZipEntry(inputFile)); //Read the input content and write to the target file while ((count = in.read(data, 0, 1024)) != -1) { out.write(data, 0, count); } //Close all the streams in.close(); out.flush(); out.close(); System.out.println("zip file "+zipFile+"is created."); } catch (Exception e) { e.printStackTrace(); } } }
