Use boolean values and readable conditions as the foundation for every branching statement in Java.

Run one block when a condition is true and another block when it is false.

Check more than two possible cases in a clear top-to-bottom order.

Use `switch` when you need to pick one path from a small set of known values such as menu choices or days of the week.

Use conditions to reject bad input and accept only values that make sense for your program.
