Quote Replace Conditional Fields For Free

One of my favourite alternatives to if...else is the ternary operator. Here expressionIfTrue will be evaluated if condition evaluates to true ; otherwise expressionIfFalse will be evaluated. The beauty of ternary operators is they can be used on the right-hand side of an assignment.

In computer science, conditionals (that is, conditional statements, conditional expressions and conditional constructs,) are programming language commands for handling decisions.Although dynamic dispatch is not usually classified as a conditional construct, it is another way to select between alternatives at runtime.

Replace Conditional with PolymorphismStep 1 is to make sure the switch statement is in a method of its own.Step 3 is to create a subclass for each leg of the conditional, overriding the parent calculateRate method.Step 4 is to turn ProjectRateType into either an interface or abstract class.More items...?Apr 4, 2016

In them, create a shared method and move code from the corresponding branch of the conditional to it. Then replace the conditional with the relevant method call. The result is that the proper implementation will be attained via polymorphism depending on the object class.

Since both the definition are different in those classes, calc_grade() will work in different way for same input from different objects. Hence it shows polymorphism.

The Ternary Operator One of my favourite alternatives to if...else is the ternary operator. Here expressionIfTrue will be evaluated if condition evaluates to true ; otherwise expressionIfFalse will be evaluated. The beauty of ternary operators is they can be used on the right-hand side of an assignment.

The conditional operator is also known as a ternary operator. The conditional statements are the decision-making statements which depends upon the output of the expression. It is represented by two symbols, i.e., '?' and ':'. As conditional operator works on three operands, so it is also known as the ternary operator.
