Hi Friend,

We have providing you a program. Try it:

import java.util.*;

public class FlamesProgram{
    static String name1 = "";
    static String name2 = "";

        public void setNames( String name1, String name2 ){
        this.name1 = name1.toLowerCase().trim().replaceAll( " ", "" );
        this.name2 = name2.toLowerCase().trim().replaceAll( " ", "" );
        }

        private String find(){
            String difference = "";
            String temName = this.name2;

            for( int i=0; i<name1.length(); i++ ){
            String a = name1.charAt(i) + "";
            if( name2.indexOf( a ) != -1 ){
                name2 = name2.replaceFirst( a, "" );}
            else{difference += a;}
            }
            difference += name2;
                this.name2 = temName;
                return difference;
        }

        public String getFLAMES(){
                String flamesResult = "";
                int difference = find().length();
                    if( difference == 0 ){
                    if( name1.equals( name2 ) )
                    return "Names are same";
                    else
                    return "Error in finding flame";
                    }
                    String fs[] = { "FRIEND", "LOVE", "AFFAIR", "MARRIAGE", "ENEMY", "SISTER/BROTHER" };
                    int k=0;
                    for( int i=5; i>0; i-- )
                    {int j=1;
                    while( j < difference ){
                    k++;
                    if( k == fs.length )
                        k = 0;
                    j++;
                    }
                        String fs1[] = new String[i];
                    int m = 0;
                    for( int l=0; l<fs.length; l++ )
                        if( l != k )
                        fs1[m++] = fs[l];
                    fs = fs1;
                    if( k == fs.length )
                        k = 0;
                        flamesResult = fs[0];
                        }
                        return flamesResult;
            }
            public static void main(String[] args){
            Scanner input=new Scanner(System.in);
            FlamesProgram fl = new FlamesProgram();
            System.out.println("Enter Name 1: ");
            name1=input.nextLine();
            System.out.println("Enter Name 2: ");
            name2 = input.nextLine();
            fl.setNames( name1, name2 );
            System.out.println( "Your Relationship is : "+ fl.getFLAMES() );
        }
    }

Thanks
