Anyway to create a spellchecker in JAVA?

Question

I'm trying to create a spellchecker in Java but without using the oop approach, like I can't use classes to achieve it. I wanna know how exactly a spellchecker algorithm works if created using only self-defined methods, arrays, loops and conditional statements. I'm making a dictionary and want to check any spelling of the words the user enters so he can also replace them and get suggestions. Here's the code I've written so far. Any help will be appreciated. Thanks

Why not use OOP? You’re handicapping yourself without it.
