Zip Files using java.util.zip Package
java provides the ‘java.util.zip‘ package to compress and decompress the data
In the below example we are using ZipOutputStream Class for output stream filter for writing files in the ZIP file format, ZipEntry Class to represent the Zip file entry and ZipInputStream Class for input stream filter for reading files in the ZIP file format
package com.javaartifacts;
import java.io.File;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.util.zip.ZipEntry;
import java.util.zip.ZipOutputStream;
public class Zip {
public static void main(String[] args){
try{
byte[] buffer = new byte[1024];
File file = new File("d:\\file.txt");
FileOutputStream fos = new FileOutputStream("d:\\file.zip");
ZipOutputStream zos = new ZipOutputStream(fos);
ZipEntry ze = new ZipEntry(file.getName());
zos.putNextEntry(ze);
FileInputStream fis = new FileInputStream(file);
int len;
while((len = fis.read(buffer)) >0){
zos.write(buffer, 0, len);
}
fis.close();
zos.closeEntry();
zos.close();
System.out.println("file zipped succesfully");
}
catch(Exception ex){
ex.printStackTrace();
}
}
}
