    Default Help with finding initials in my Java program...

    I need help on a code where i get my input from a text document(i cant remember what the input is called) and from there i must get the first initials of each word.For example "John The Kid" output should be JTK. I think my main problem im having is the for loop and or maybe the code for actually getting the initials of each word.
    I can only use charAt indexOf and substring for the code.As much explanation would help i really would like to understand what i need to help and why i am doing it.Thanks
    This is my object file.

    What does this code do?

    Take a step back from the computer and think about what you're trying to do. How do you do it without a computer? Pretend you have a really dumb friend who has no idea how to figure out what the initials of a given set of words or names are. Write out step-by-step instructions that your friend could follow (remember how dumb he is). When you have that, you'll have an algorithm that you can start writing code for.

    Since you never change the value of new_word or original_ in your main method what is the purpose of passing empty Strings to your Acronym object?

    new_word is for the initials like "rain every few" new_word would equal "rew" and original_ is supose to get me the end initals but backwords so original should return "wyn". I didnt mention this other part of the program but i figured i could figure that out once ive figured the rest of the program out.
