package com.tutorial4u;

public class DeleteRepetedCharacterFromTwoString {

     public static void main(String[] args) {

           String s1 = "Tutorial";

        String s2 = "TotalJava";

        System.out.println("String s1 is = " + s1 + " , String s2 is = " + s2);

        char c1[] = s1.toCharArray();

        char c2[] = s2.toCharArray();

       

        for (int i = 0; i < c1.length; i++) {

          

               boolean charMatch = false;

              

               for (int j = 0; j < c2.length; j++) {

                     if ((String.valueOf(c1[i])).toLowerCase().equals(

                                   ((String.valueOf(c2[j])).toLowerCase()))) {

                       charMatch = true;

                            break;

                     }

               }

               if (charMatch) {

                     s1 = s1.replaceAll(String.valueOf(c1[i]).toUpperCase(), "");

                     s1 = s1.replaceAll(String.valueOf(c1[i]).toLowerCase(), "");

                     s2 = s2.replaceAll(String.valueOf(c1[i]).toLowerCase(), "");

                     s2 = s2.replaceAll(String.valueOf(c1[i]).toUpperCase(), "");

               }

        }

        System.out.println("After deleted s1 = " + s1 + ",  after deleted s2 = " + s2);

     }

}

Output :

String s1 is = Tutorial , String s2 is = TotalJava

After deleted s1 = uri,  after deleted s2 = Jv
