Alert: You can change the procedure if you want because this code won't give you the desire output but only give you the main idea..cheers.. :)

Code:

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.util.*;
public class Uva_272 {
    public static void main(String args[]) throws IOException{
    Scanner in=new Scanner(System.in);
    InputStreamReader In=new InputStreamReader(System.in);
    BufferedReader br=new BufferedReader(In);
    StringBuilder str=new StringBuilder();
    String tomato="";
    int v=0;
    while((tomato=br.readLine())!=null){
    for(int i=0;i<tomato.length();i++){
    if(tomato.charAt(i)=='\"'){
    v++;
    if(v%2!=0){
    str.append("``");
    }else{
    str.append("\'\'");
    }
    }else{
    str.append(tomato.charAt(i));
    }
    }
    System.out.println(str);
    str.append("\n");
    }
    } 
    }
