java.util.zip.Deflater.end() Method Example
Description
The java.util.zip.Deflater.end() method closes the compressor and discards any unprocessed input. This method should be called when the compressor is no longer being used, but will also be called automatically by the finalize() method. Once this method is called, the behavior of the Deflater object is undefined.
Declaration
Following is the declaration for java.util.zip.Deflater.end() method.
public void end()
Example
The following example shows the usage of java.util.zip.Deflater.end() method.
package com.tutorialspoint; import java.io.UnsupportedEncodingException; import java.util.zip.DataFormatException; import java.util.zip.Deflater; import java.util.zip.Inflater; public class DeflaterDemo { public static void main(String[] args) throws DataFormatException, UnsupportedEncodingException { String message = "Welcome to TutorialsPoint.com;" +"Welcome to TutorialsPoint.com;" +"Welcome to TutorialsPoint.com;" +"Welcome to TutorialsPoint.com;" +"Welcome to TutorialsPoint.com;" +"Welcome to TutorialsPoint.com;" +"Welcome to TutorialsPoint.com;" +"Welcome to TutorialsPoint.com;" +"Welcome to TutorialsPoint.com;" +"Welcome to TutorialsPoint.com;"; System.out.println("Original Message length : " + message.length()); byte[] input = message.getBytes("UTF-8"); // Compress the bytes byte[] output = new byte[1024]; Deflater deflater = new Deflater(); deflater.setInput(input); deflater.finish(); int compressedDataLength = deflater.deflate(output); deflater.end(); System.out.println("Compressed Message length : " + compressedDataLength); // Decompress the bytes Inflater inflater = new Inflater(); inflater.setInput(output, 0, compressedDataLength); byte[] result = new byte[1024]; int resultLength = inflater.inflate(result); inflater.end(); // Decode the bytes into a String message = new String(result, 0, resultLength, "UTF-8"); System.out.println("UnCompressed Message length : " + message.length()); } }
Let us compile and run the above program, this will produce the following result −
Original Message length : 300 Compressed Message length : 42 UnCompressed Message length : 300Print
