4 archive.createEntries(corpus);
5 archive.save(zipFile);
6 }
7} catch (IOException ex) {
8 System.out.println(ex);

1try (FileInputStream zipFile = new FileInputStream(dataDir + "CompressDirectory_out.zip")) {
2 try (Archive archive = new Archive(zipFile)) {
3 archive.extractToDirectory(dataDir + "DecompressFolder_out");
4 }
5} catch (IOException ex) {
6 System.out.println(ex);
7}Compress Files by File Info
1try (FileOutputStream zipFile = new FileOutputStream(dataDir + "CompressFilesByFileInfo_out.zip")) {
2 File fi1 = new File(dataDir + "alice29.txt");
3 File fi2 = new File(dataDir + "fields.c");
4 try (Archive archive = new Archive()) {
5 archive.createEntry("alice29.txt", fi1);
6 archive.createEntry("fields.c", fi2);
7 ArchiveSaveOptions options = new ArchiveSaveOptions();
8 options.setEncoding(StandardCharsets.US_ASCII);
9 archive.save(zipFile, options);
10 }
11} catch (IOException ex) {
12 System.out.println(ex);
13}Extract Archives with Different Entry Archives
1try (FileInputStream zipFile = new FileInputStream(dataDir + "\\different_password.zip")) {
2 try (Archive archive = new Archive(zipFile)) {
3 archive.getEntries().get(0).extract(dataDir + "alice29_extracted_pass_out.txt", "first_pass");
4 archive.getEntries().get(1).extract(dataDir + "asyoulik_extracted_pass_out.txt", "second_pass");
