Here my code :

My question is HOW do i remove the duplicates in my final answer.

import java.io.*;

import java.util.*;

public class Main {

//List for Collecting permutations of word

static ArrayList perms;

//This method calculates the permutations of the string using recursion and stores in the above list.

static void genPerms(char str[], int ind){

if(ind==str.length-1){

perms.add(String.valueOf(str));

return;

}

for(int i=ind;i

char ch = str[i];

str[i] = str[ind];

str[ind] = ch;

genPerms(str, ind+1);

ch = str[i];

str[i] = str[ind];

str[ind] = ch;

}

}

public static void main(String[] args) throws IOException {

//Reading the dictionary into a set

String dict = args[0];

BufferedReader f1 = new BufferedReader(new FileReader(new File(dict)));

String word;

HashSet hs = new HashSet();

while((word = f1.readLine())!=null){

hs.add(word);

}

//Reading the words

String jumbles = args[1];

BufferedReader f2 = new BufferedReader(new FileReader(new File(jumbles)));

//List for storing final answer

ArrayList fans = new ArrayList();

//Iterating through all the jumble words

while((word = f2.readLine())!=null){

//finding permutations

perms = new ArrayList();

genPerms(word.toCharArray(),0);

String ans = word;

//Storing perms in a List

ArrayList bunch = new ArrayList();

for(String x : perms){

if(hs.contains(x)){

bunch.add(x);

}

}

//Sorting the list

Collections.sort(bunch);

//Calculating the answer

for(String x : bunch){

ans = ans+" "+x;

}

fans.add(ans);

}

//Sorting the answer vertically

Collections.sort(fans);

for(String x : fans){

System.out.println(x);

}

}

}
