What is the best approach to capitalize words in a string?

I'm trying to .capitalize all string inputs, excluding small words such as "Of", "The" or "And".

I can't figure out why the code isn't working properly.

def titleize(x)  capitalized = x.split.each do |i|    if i.length >= 2      if i == "of" || "the" || "and"        next      else        i.capitalize!      end    else      next    end  end  capitalized.join(' ')end

Here's my Rspec output:

Failures:

 1) Simon says titleize capitalizes a word Failure/Error: expect(titleize("jaws")).to eq("Jaws")   expected: "Jaws"        got: "jaws"   (compared using ==)

Is there a function built into Java that capitalizes the first character of each word in a String, and does not affect the others?

Examples:

• jon skeet -> Jon Skeet
• miles o'Brien -> Miles O'Brien (B remains capital, this rules out Title Case)
• old mcdonald -> Old Mcdonald*

*(Old McDonald would be find too, but I don't expect it to be THAT smart.)

A quick look at the Java String Documentation reveals only toUpperCase() and toLowerCase(), which of course do not provide the desired behavior. Naturally, Google results are dominated by those two functions. It seems like a wheel that must have been invented already, so it couldn't hurt to ask so I can use it in the future.

I'm looking for an example of how to capitalize the first letter of a string being entered into a text field. Normally, this is done on the entire field with a function, regex, OnBlur, OnChange, etc. I want to capitalize the first letter while the user is still typing.

For instance, if I'm typing the word "cat", the user should press 'c', and then by the time he presses 'a', the C should be capitalized in the field.

I think what I'm going for might be possible with keyup or keypress but I'm not sure where to start.

Anyone have an example for me?

What is wrong with this function? I am lost thanks for help.

function titleCase(str) { var splitStr = str.toLowerCase().split(' '); for (var i = 0; i < splitStr.length; i++) {   if (splitStr.length[i] < splitStr.length) {     splitStr[i].charAt(0).toUpperCase();        }      str = splitStr.join(' ');  }return str;}titleCase("I'm a little tea pot");
