Another suggestion  Let s say you have two same words in the String  String s1    who is my brother  who is your brother      I don t mind the meaning of the sentence    replace function will change every string is given in the first parameter to the second parameter  System out println s1 replace  brother    sister        who is my sister  who is your sister   and you can use also replaceAll method for the same result  System out println s1 replace  brother    sister        who is my sister  who is your sister   if you want to change just the first string which is positioned earlier   System out println s1 replaceFirst  brother    sister        whos is my sister  who is your brother
