Write a program in which a method with the heading public static void capitalize(String s) calls a method with the heading public static char toUpperCase(char ch) that if ch is a lowercase letter, the method will return the corresponding uppercase letter, if ch is an uppercase letter, the method will return the uppercase letter, and if ch is not a letter, the method returns the same value of ch. Thus, for instance, toUpperCase('a') returns A and toUpperCase('$') returns '$'. Note that the uppercase letters have a unicode (ascii code) value that is 32 lower than the corresponding lowercase ones.

Your main method should send the string "my country tis of thee, Sweet land of liberty, Of thee I sing" to capitalize() which using toUpperCase() capitalizes the first letter in every word. Note the beginning of a word is defined as follows: the current letter is not a blank and the previous letter is a blank. The first character in the sentence should be treated separately. There can be more than one blank separating words. Method capitalize() should print: "My Country Tis Of Thee, Sweet Land Of Liberty, Of Thee I Sing."
Note that your program should work for any sentence inputted.
