A
org.xerial.snappy.Snappy class allows you to compress and decompress byte arrays.
Here is an example Java program, HelloSnappy.java:
// HelloSnappy.java
// Copyright (c) FYIcenter.com
import org.xerial.snappy.Snappy;
public class HelloSnappy {
public static void main(String[] args) throws Exception {
String input = "Hello snappy-java! Snappy-java is a JNI-based wrapper"
+ " of Snappy, a fast compresser/decompresser.";
byte[] original = input.getBytes("UTF-8");
byte[] compressed = Snappy.compress(original);
byte[] uncompressed = Snappy.uncompress(compressed);
String result = new String(uncompressed, "UTF-8");
System.out.println(result);
}
}
Run this Java program with the Snappy-Java JAR file:
fyicenter$ java -cp snappy-java-1.1.8.4.jar HelloSnappy.java Hello snappy-java! Snappy-java is a JNI-based wrapper of Snappy, a fast compresser/decompresser.
The Java program compress and decompress a message correctly.
