ตัวอย่าง GZip
ในตัวอย่างจะทำการบีบอัดไฟล์ "C:\\users\\nopphanan7\\Directory1\\photo.jpg" ไปเป็น gzip ไฟล์ชื่อ "C:\\users\\nopphanan7\\MyGZFile.gz".
package demo.compress; import java.io.FileInputStream; import java.io.FileOutputStream; import java.io.IOException; import java.util.zip.GZIPOutputStream; public class CompressGZipFileExample { private static final String OUTPUT_GZIP_FILE = "C:\\users\\nopphanan7\\MyGZFile.gz"; private static final String SOURCE_FILE = "C:\\users\\nopphanan7\\Directory1\\photo.jpg"; /** * @param args */ public static void main(String[] args) { CompressGZipFileExample gZip = new CompressGZipFileExample(); gZip.gzipIt(); } /** * GZip it * * @param zipFile output GZip file location */ public void gzipIt() { byte[] buffer = new byte[1024]; try { GZIPOutputStream gzos = new GZIPOutputStream(new FileOutputStream(OUTPUT_GZIP_FILE)); FileInputStream in = new FileInputStream(SOURCE_FILE); int len; while ((len = in.read(buffer)) > 0) { gzos.write(buffer, 0, len); } in.close(); gzos.finish(); gzos.close(); System.out.println("Compress file with GZip is Done"); } catch (IOException ex) { ex.printStackTrace(); } } }ผลลัพธ์ที่ได้คือ
Compress file with GZip is Done
