Can you please help with this problem, she want us to use the unicode for the methods but has never told us how to do it and not helping, 

Thank you!

Write a program that asks the user to enter a character. Then pass the character to the following methods. a) isVowel() – returns true if the character is a vowel b) isConsonant()- returns true if the character is a consonant c) changeCase() - if the character is lower case then change it to upper case and if the character is in upper case then change it to lower case. Example output is given below: Enter a character a a is a vowel a is not a consonant a is equivalent to A Note: Java represents character using Unicode encoding and A' to Z' is represented by numbers 65 to 90 and 'a' to 'z' is represented by numbers 97 to 122. So to convert 'A' to 'a' you need to add (97-65) to A and then cast it to Character type since the addition will change its type to integer. You can use the following code to read a character from console. When you call charAt(i) method for any String it returns the character at index i. The index of first character is 0, the index of second character is 1 and so on.
