Need Help

[ing]

I'm building a program that allows a user to select a word from a sentence and replace it with a word, which a user also enters. i also want to all in-case sensitive.

So for example:

a user enter the following
sentence: Hello my name is Peter Peters
wordSelect: peters
replacementWord: Pan

Result: Hello my name is Peter Pan

can anyone help?

This should work. All of my tests worked. Let me know if this is what you need. You'll just have to add in the user input.

Code:

  static String repWord(String sentence, String wordSelect, String replacementWord) {
    String temp;
    String[] splitSentence;
    temp = sentence.toLowerCase();
    wordSelect = wordSelect.toLowerCase();
    splitSentence = temp.split(wordSelect);
    int count = 0;
    String finalSentence = "";
    for (String x : splitSentence) {
      finalSentence += sentence.substring(count, count + x.length()) + replacementWord;
      count += x.length() + wordSelect.length();
    }
    if (temp.lastIndexOf(wordSelect) != temp.length() - wordSelect.length()) {
      finalSentence = finalSentence.substring(0, finalSentence.length() - replacementWord.length());
    }
    return finalSentence;
  }

  public static void main(String[] args) {

    String sentence = "Hello my name is Peter Peters";
    String wordSelect = "peters";
    String replacementWord = "Pan";
    String output;
    output = repWord(sentence, wordSelect, replacementWord);
    System.out.println(output);

  }

Yeah thanks, it great, thanks. Just one question is it possiible to not have the "static String repWord()".

Possible....


just make an instance of class in your main method and call method on that instance.

How do make it so that it doesnt replace words that don't match. for example:

sentence: Hello my name is Peter Peters. Peters's
wordSelect: peters
replacementWord: Pan

Result: Hello my name is Peter Pan. Peters's

Thanks

You could just make it so that whatever word you go to search for you add a space before and after it. But then if the word comes before a comma or period it wont change it. You would have to make a case statement and have it grab the letter after the word each time and if it is a space, comma, or period allow it, but if it is anything else don't touch it. With this extra overhead it may be more beneficial to add regular expressions into it. Goodluck.
