Question

Beginner here. Sorry for the vague title but the code should put my question into perspective.

public static void main(String [] args)
{
    String sentence = "hi. how are you! i'm just dandy.";
    String tokenSent;

    tokenSent = sentenceCapitalizer(sentence);

    System.out.println(tokenSent);
}

public static String sentenceCapitalizer(String theSentence)
{
    StringTokenizer strTokenizer = new StringTokenizer(theSentence, ".!", true);

    String token = null;
    String totalToken = "";
    String ch = "";

    while(strTokenizer.hasMoreTokens())
    {
        token = strTokenizer.nextToken().trim();

        token = token.replace(token.charAt(0), Character.toUpperCase(token.charAt(0)));

        StringBuilder str = new StringBuilder(token);
        str.append(" ");

        totalToken += str;

    }

    return totalToken; 
}

OUTPUT AS IS: Hi . How are you ! I’m just dandy .

I was able to capitalize the first letter of each sentence but I’m wanting the output to keep the same format as the original String. The problem is that it puts a space before and after the ending punctuation. Is there any way to fix this problem using only a StringBuilder and/or StringTokenizer? Thank you for your time.

Answer 1

You can do this.

String delim = ".!";
StringTokenizer strTokenizer = new StringTokenizer(theSentence, delim, true);

Then,

if(delim.contains(token))
    str.append(" ");
