             String result= res.getHeader('result');
        
              //Get body as a blob
              Blob ResponseString=res.getBodyAsBlob();
              System.debug('Response str is   '+ResponseString);  
              //save file in Attachment
              attachment DataFile = new attachment();
              //store file as a zip file        
              DataFile.Name = 'xyzzipfile.zip';       
              DataFile.ParentId ='a049000000HRSkc';                            
              DataFile.body = ResponseString; 
              DataFile.contentType='application/x-zip-compressed';
              insert DataFile;   
Similer to above method you  can create zip file in apex

@Ravikant kedia:
  My usecase is download all the attachements on click of visualforce button.
For that we need to create a zip file which contains all the attachments.
I need a sample code for my usecase.


Thanks in advance,
Karthick

You can use the Zippex library to do this. It's open source. https://github.com/pdalcol/Zippex 
//First create a blank zip archive
Zippex zip = new Zippex();

//Add files one by one using the addFile() method
//The first parameter is the filename
//The second parameter is a Blob with the file contents
//The thrid parameter is the file chechsum, you can pass null
zip.addFile('sampleFile1.txt', Blob.valueOf('Sample text1.'), null);
zip.addFile('sampleFile2.txt', Blob.valueOf('Sample text2.'), null);
...
//Finally fetch the resulting zip file
Blob zipBlob = zip.getZipArchive();
