Closes the compressor and discards any unprocessed input.

Usage

From source file:Main.java

public static void main(String[] args) throws Exception { // main method
    // Encode a String into bytes
    String inputString = "this is a test";
    byte[] input = inputString.getBytes("UTF-8");

    // Compress the bytes
    byte[] output1 = new byte[input.length];
    Deflater compresser = new Deflater();
    compresser.setInput(input);/*w ww .  ja  va2s  . c o  m*/
    compresser.finish();
    int compressedDataLength = compresser.deflate(output1);
    compresser.end();

    String str = new String(Base64.getEncoder().encode(output1));
    System.out.println("Deflated String:" + str);

    byte[] output2 = Base64.getDecoder().decode(str);

    // Decompress the bytes
    Inflater decompresser = new Inflater();
    decompresser.setInput(output2);
    byte[] result = str.getBytes();
    int resultLength = decompresser.inflate(result);
    decompresser.end();

    // Decode the bytes into a String
    String outputString = new String(result, 0, resultLength, "UTF-8");
    System.out.println("Deflated String:" + outputString);
