/**Counting the appearances of a given
word in a text
We have seen how to read in and manipulate characters and character strings and how to use the classes
String and StringTokenizer. Use these to read in a word and then other text from the keyboard. Count the occurrences of the word that you read in at the beginning. Your program should be case insensitive; this means that
you should convert the original word to pure upper case OR lower case and compare each token that you separate to this same case using toUpperCase() or toLowerCase(). Your program should keep checking text until you type �The End� by itself on one line**/
