so it is safe to say that == is best used for int variable and .equals() for Strings?

Yes. Not only is .equals() used for strings, using == doesn’t necessarily give you the result you want. .equals() compares the values of strings for equality, while == would compare the references (the addresses in memory of where the strings are stored) of the strings for equality. See a much longer and more detailed conversation here.

So do you use .equals() for char’s and boolean’s as well? Or is it just reserved for Strings?

It’s for strings,
for numbers, chars, and booleans == works fine.
(Although if you make your own objects and you want to be able to check if they are equal, you’d probably write a equals method for those.)
