All input will be given to you either as a command-line argument or typed in from the keyboard. Below you will find directions for each class you need to create. Please make sure that the class name and java file name match the name 1, ContainsAnyCase This program will accept two user inputted values that are strings. The first user input will be a single word the second user input will be a sentence of random words.
