What is the difference between a widening and narrowing conversion in Java?
Accordingly, what is narrowing and widening in Java?
Widening is taking place when a small primitive type value is automatically accommodated in a bigger/wider primitive data type. Widening is taking place when a reference variable of a subclass is automatically accommodated in the reference variable of its superclass.
Additionally, what do you mean by type conversion? In computer science, type conversion or typecasting refers to changing an entity of one datatype into another. There are two types of conversion: implicit and explicit. Explicit type conversion can also be achieved with separately defined conversion routines such as an overloaded object constructor.
Additionally, what is narrowing in Java?
Narrowing refers to passing a higher size data type like int to a lower size data type like short. It may lead to data loss. Casting is required for narrowing conversion. Following program output will be 44.
What is automatic type conversion?
Also known as 'automatic type conversion'. Done by the compiler on its own, without any external trigger from the user. Generally takes place when in an expression more than one data type is present. All the data types of the variables are upgraded to the data type of the variable with largest data type.
