As the compiler says, the case expressions must be constant expressions. You can't use an array element as a case expression. You can simply use an if else if else clause instead.
You can't use non-constant expressions in case statements. An alternative approach is to build a map from values to the actions. So instead of this (which doesn't actually make any sense to me).
