Java batch download to generate ZIP files

 

Download the two files at the same time using the following code:

ImportJava. Io. file;
ImportJava. Io. fileinputstream;

ImportJava. Io. fileoutputstream;

ImportJava.util.zip. zipentry;

ImportJava.util.zip. zipoutputstream;

Public
ClassZipoutputstreamdemo {

Public
Static
VoidMain (string [] ARGs)
ThrowsException {

Byte[] Buffer =
New
Byte[1024];

// The generated ZIP file name is demo.Zip

String strzipname =
"Demo.zip ";

Zipoutputstream out =
NewZipoutputstream (New
Fileoutputstream (strzipname ));

// Result of the two files to be downloaded at the same time.Txt
, Source.Txt

File [] file1 = {New
File ("result.txt "),New
File ("source.txt ")};

For(Int
I = 0; I <file1.length; I ++ ){

Fileinputstream FCM =
NewFileinputstream (file1 [I]);

Out. putnextentry (New
Zipentry (file1 [I]. getname ()));

IntLen;

// Read the content of the object to be downloaded and package itZipFile

While(LEN = FCM. Read (buffer)> 0 ){

Out. Write (buffer, 0, Len );

}

Out. closeentry ();

FCM. Close ();

}

Out. Close ();

System.Out. Println ("demo.zip created ");

}
