How to convert Header Case String to Upper Case String?

Example

Let's convert the string "Hello World" to Upper Case String.

First, we need to split the string into words.

String	Words
Hello World	Hello, World

Now, we need to convert each word to upper case.

Hello, World	HELLO, WORLD

Finally, we need to join the words together. In this case, the final Upper Case String is HELLO WORLD. This is the Upper Case String representation of the string "Hello World".
