SHOW ANSWERWhich of this statement is incorrect?
switch statement is more efficient than a set of nested ifs
two case constants in the same switch can have identical values
switch statement can only test for equality, whereas if statement can evaluate any type of boolean expression
it is possible to create a nested switch statements
