How would I perform a password check where the importance of case sensitivity can't be ignored by uppercasing everything
If the password is, let's say 5d7988B, with the uppercase method we could also write 5D7988b which would result in a correct password that is actually wrong.

Hi Ernest Nezić,
Let me know if I’m not understanding your question correctly, but if case sensitivity is important (as such is with the case of passwords) you simply would not call toUppercase() on the string. You would just compare the user’s input as is against the password stored in the database.
In reality, you would hash the user’s input and compare it against a hashed password within your database, but the point I’m trying to make is that you would not manipulate the user’s input with the toUppercase or toLowercase methods.
Hope that helps. If not, let me know.
