Program: How to decompress the compressed objects using zip utility?


Description:

This example shows how to decompress the compressed objects. Previous example shows how to compress objects and store it to the file.


Code:
package com.java2novice.zip;

import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.IOException;
import java.io.ObjectInputStream;
import java.util.zip.GZIPInputStream;

public class RetrieveMyObjects {
	
	public static void main(String a[]){

		FileInputStream fis = null;
		GZIPInputStream gs = null;
		ObjectInputStream ois = null;
		try {
			fis = new FileInputStream("C:/MyObjectStore");
			gs = new GZIPInputStream(fis);
			ois = new ObjectInputStream(gs);
			Mobile m1 = (Mobile) ois.readObject();
			System.out.println(m1.getNumber()+"   "+m1.getOwner());
			Mobile m2 = (Mobile) ois.readObject();
			System.out.println(m2.getNumber()+"   "+m2.getOwner());
		} catch (FileNotFoundException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		} catch (IOException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		} catch (ClassNotFoundException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		} finally{
			try{
				if(ois != null) ois.close();
				if(fis != null) fis.close();
			} catch (Exception ex){}
		}

	}
}


class Mobile implements Serializable{
	
	private String number;
	private String owner;
	
	public Mobile(String num, String own){
		this.number = num;
		this.owner = own;
	}
	
	public String getNumber() {
		return number;
	}
	public void setNumber(String number) {
		this.number = number;
	}
	public String getOwner() {
		return owner;
	}
	public void setOwner(String owner) {
		this.owner = owner;
	}
	
}
