Java Java Objects (Retired) Harnessing the Power of Objects Methods and Constants

Constants and Final?

Hello-

As explained in the video, constants are values that can never change. Later in the video, we were introduced to the 'final' keyword that prevents your code from being changed.

Why cant we just use the 'final' keyword instead of using constants when writing something that can't and shouldn't be changed? Do constants and 'final' do the same thing?

Help is appreciated!

To my knowledge, a constant is the concept of what the "final" keyword performs. There is a "const" keyword in Java, but it is not used. So essentially, when you label a variable with final, you are creating a constant.
