if one int is less than or greater than another int by one

I'm trying to create a boolean that will return true/false based on if one int (which is a variable) is less than or greater than another int (which is a variable) by one. What I'm thinking of coding seems overly complicated and I was wondering if there was something that could do those calculations for me, like a method of some sort or a simple addition to a method. There's nothing in the int java docs that I can find.


Thanks.

Why don't you show us your code and perhaps we can take a look at it.

Sometimes once you have a method signature the implementation writes itself:

It can also be helpful to try a simpler problem first. For example, what if you ignore the "or greater than" part? Can you write a method that returns true if one int is less than the other by one? Hint: is there another way to write "less than the other by one"?

Don't overthink this problem, the solution is very very simple...

The text almost literally says it: check if the difference between two numbers is 1 or -1
Now you'll just have to convert that statement to Java code.
