Online Lower Case Converter

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.

#inputmy_string = 'abcdefgABCDEFGHIJKLMNOP'

how would one extract all the UPPER from a string?

#outputmy_upper = 'ABCDEFGHIJKLMNOP'

I am trying to convert all lowercase to uppercase letter, using the ASCII table! It is very easy to deal and i have figured out the code. Problem is, that if there is a space between the words, then the program will only change the first word and after the space it will not print anything.

Example
Word: Andreas Gives: ANDREAS
Word: TeSt123Ha Gives: TEST123HA
BUT!!!
Word: Hello 45 Gives: HELLO
after the space it prints nothing!

I know that the space in ASCII table is equal to 32, and in my code i tell the program that if the current code that you are reading is not between 97 and 122, then don't perform any changes!

But it is still not working!

char currentletter;int i;for (i=0; i<49; i++)    {    currentletter = str[i];    if ((currentletter > 96) && (currentletter < 123))    {        char newletter;        newletter = currentletter - 32;        str[i] = newletter;    }    else    {        str[i] = currentletter;    }}printf("%s\n", str);

I have a little doubt about QR character list. A summary of the specification is here:

Numeric only    Max. 7,089 characters (0, 1, 2, 3, 4, 5, 6, 7, 8, 9)Alphanumeric    Max. 4,296 characters (0–9, A–Z [upper-case only], space, $, %, *, +, -, ., /, :)Binary/byte     Max. 2,953 characters (8-bit bytes) (23624 bits)Kanji/Kana  Max. 1,817 characters

How does it works for the characters out side these lists, like lower case letters or ~,? etc.?
As for example : The QR code for a~?bC generated from here:
enter image description here

How does it work? Because few characters ~ ? a b are not listed in the standard QR code character list.

I've got pretty much this error: AngularJS ngSanitize Error

short version: "lowercase is not a function".

While my application has AngularJS enforced to 1.4.9, we didn't enforce angular-sanitize, so it resolves to 1.7.0 and on that version of AngularJS lowercase function doesn't exist anymore, producing an error.

Probably by forcing angular-sanitize to a fixed version would fix that, but I want to go beyond fixing it and understand what is causing the problem and why, because I find a few inconsistencies.

• AngularJS is forced to 1.4.9. bower-components folder holds this version, build folder after compiling also holds this version, developer panel on Chrome show only this version is fetched. This version does have lowercase method.

• Angular-sanitize has angular 1.7.0 as a dependency, but it's never downloaded, never. Not in any single folder or subfolder on the entire project, not at compiling, not from Chrome either. So I guess the only angular.js he's got access to is 1.4.9, which does have lowercase method.

I don't quite understand why then "lowercase is not a function" error appears if the only available angular.js still has that method. Also I don't understand why angular-sanitize 1.7.0 demanding angular 1.7.0 uses non-existing methods on AngularJS 1.7.0 (Angular developers mistake? but I find hard to believe it.)

Probably sanitize is downloading and accessing angular 1.7.0 somehow, but I would like to know how. Just out of curiosity. And also to confirm if this is an angular developers mistake or if there's something I've missed.
