Compress a String and Save as a Gzip File

See more Gzip Examples

This example demonstrates how to use the CompressStringToFile method to compress a string and write the result directly to a Gzip (.gz) file.

The input string is first converted to its byte representation using the specified character set (in this case, UTF-8). The resulting bytes are then compressed using the Gzip format, and the compressed output is written directly to the specified file.

This method is convenient when you want to generate a compressed file from in-memory text without needing intermediate objects such as BinData or StringBuilder.

import com.chilkatsoft.*;

public class ChilkatExample {

  static {
    try {
        System.loadLibrary("chilkat");
    } catch (UnsatisfiedLinkError e) {
      System.err.println("Native code library failed to load.\n" + e);
      System.exit(1);
    }
  }

  public static void main(String argv[])
  {
    boolean success = false;

    // This example demonstrates how to compress a string and save the result
    // directly to a Gzip (.gz) file.

    CkGzip gzip = new CkGzip();

    // The string to be compressed:
    String inputStr = "The quick brown fox jumps over the lazy dog.";

    // Compress the string using UTF-8 and write to a file:
    success = gzip.CompressStringToFile(inputStr,"utf-8","output.gz");
    if (success == false) {
        System.out.println(gzip.lastErrorText());
        return;
        }

    System.out.println("Compression successful.");
    System.out.println("Gzip file written to output.gz");
  }
