DeflaterInputStream and InflaterOutputStream in Java

By Arvind Rai, April 17, 2013

DeflaterInputStream and InflaterOutputStream belong to jdk 1.6. DeflaterInputStream compresses data in DEFLATE format and provides input stream. Find the example for DeflaterInputStream.
DeflaterInputStreamTest.java

package com.concretepage;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.util.zip.DeflaterInputStream;
import java.util.zip.DeflaterOutputStream;
public class DeflaterInputStreamTest {
    public static void main(String[] args) throws Exception {
        FileInputStream in = new FileInputStream("D:\\page\\file.txt");
        FileOutputStream out = new FileOutputStream("D:\\page\\file.dfl");
        DeflaterInputStream dis = new DeflaterInputStream(in);
        int ch=0;
        while ((ch = in.read())!=-1){
           ch = in.read();
           out.write(ch);
        }
        dis.close();
        in.close();
        out.close();
      }   
 }

InflaterOutputStream uncompresses DEFLATE format data and provides output stream. Find the example for InflaterOutputStream.
InflaterOutputStreamTest.java

package com.concretepage;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.util.zip.InflaterOutputStream;
public class InflaterOutputStreamTest {
    public static void main(String[] args) throws Exception {
        FileInputStream in = new FileInputStream("D:\\page\\file.dfl");
        FileOutputStream out = new FileOutputStream("D:\\page\\dfloutput.txt");
        InflaterOutputStream ios = new InflaterOutputStream(out);
        int ch=0;
        while ((ch = in.read())!=-1){
           ch = in.read();
           ios.write(ch);
        }
        ios.close();
        in.close();
        out.close();
      }   
 }
