I have an assignment in my computer science course and i can't figure out how to get this code to work to these guide line
this is the code
and these are the guide lines i am suppose to follow
Write a Java program that asks the user to enter characters, one at a time, from the command line. The program should end when the period (".") character is entered and the number of case changes that occurred should be displayed. As each character is entered, the program
o should change each lower case character to upper case after it is entered.
o should change each upper case character to lower case after it is entered.
o should output the resulting change to the monitor after each character is input.
o should not make any changes to other characters such as @ or $).
o should instruct the user to enter the period (.) character to end the program.
Help would be awesome because i am really stumped by this one
the most trouble i am having is finding a way to have the program reconize that a period has been entered and adding the strings entered together.
