  • If the first condition is false, use else to specify a different condition to be tested.

WhatAre you more effective than if statements?

A switch statement is more efficient than a list. ofnested Ifs The compiler canDo this because it knows the case constants are all of the same type. It simply must be compared with the switch expression for equality, while inCase ofIf expressions are not defined, the compiler does not have such knowledge.

What can you do? I avoid if-else?
