I break string into char array. Loop. If char equals to whitespace and next char dosn't equal to whitespace than replace next char with upperCase the same char. In the end I return to String, although you can print it thru loop of char array.

Hint: Array[].split() don't stores space between words. If theres more than one space between words, the program should put it.

Why can't we do this instead of turning the string to a char array?

String[] split = s.split(" ");

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

            char firstLetter = split[i].charAt(0); //get the first letter
            char toUpperCase = Character.toUpperCase(firstLetter); //set the first letter to upperCase

            split[i] = split[i].replace(firstLetter, toUpperCase);
            System.out.print((i == split.length - 1)? split[i] : split[i] + " ");
        }

Java Program to Capitalize the first character of each word in a String This works and is an interesting method.

This one is only hard in the sense that you have to use String methods that we haven't used or seen before. Google is your friend. Think about what you need to do with the string, and if you ask the right question Google will display the answer. Google (or other search tool) is an essential tool for any programming language. Nobody expects a programmer to memorize every single method or function in existence. You'll have to get used to looking things up.

So if any of you were confused by the lackluster instructions on this one, here are some additional parameters that might help you: - You need to account for if the user input has more than one space inbetween the words. - When you print out the text, you only need one space between words, so you can eliminate the extra spaces. (You don't need to print out the extra spaces exactly like the input, which I did, and in fact won't pass) Some tips: - Use split(). - Then trim() the spaces. - Learn about substring() or convert the trimmed array into individual char arrays and toUpperCase() on the first letter. - And (credit to Steve, somewhere in the comments) split by "\\s+". Which notates splitting by one or more white spaces. If you want to look this up, its a regex expression.

As someone previously said, another forced self-learning, but this one is pretty ridiculous in its scope (stackOverFlow suggests 20+ ways to solve it & only understand parts of each solutions). Got it to pass, but gonna have to some more time studying these methods and their logic. Fooyee!!

Well, I have seen many comments about changing the string itself, but I think such a choice is not that favorable after all. For me, I decided to make a different string variable: resultSentence. then I wrote a method that returns the indices of the first letters in each word in the sentence aka the indices that come right after the space character. Using the return list, I can know which of the characters need to be uppercase and which are lowercase.

Yes these are your best friends for this task: .split() .charAt() .substring() and use just System.out.print instead of println, depending on your code. As an additional note, make sure to test your answer with a string that has 2 or more spaces. That one got me spining for some minutes.

For this task you need to first Google: 1. Scanner scanner = new Scanner("string"); //take a sentence and divide it to single words. 2. Character.toUpperCase(i); // take a letter at index(i) and turn it into upperCaseLetter. 3. "string".subString(i); 4. StringBuilder - it helps to learn about it as well but not mandatory.
