Hi, so I was able to do what I want but in a wrong way.. Basically what the program does it get a prefix and the word to add it into. Then the sentence. Then the sentence is split into an array. Then the loops finds the word in the array and add the prefix to it. I was able to do it and print. But my problem is that I need to return it instead of print. How am I going to do it? Sorry I'm new with java.

Ignoring your code for a moment. If you want to return a string then you should put all that logic in a method

public String whatEverYouAreDoing(String word, String prefix, String sentence)
{
      //logic

     return (a string);
}

All you need to do is to compose back the original string using "+" operator to concatenate strings.

...


String[] arraystr = sentences.split (" ");

String new_sentence = "";


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

        {

            if (arraystr [i].equals (word))

                arraystr[i] = prefix + arraystr[i];

            new_sentence += (arraystr [i] + " ");

        }

}


return new_sentence;
