In Java, there are two types of casting:Widening Casting (automatically) – converting a smaller type to a larger type size. byte -> short -> char -> int -> long -> float -> double.Narrowing Casting (manually) – converting a larger type to a smaller size type. double -> float -> long -> int -> char -> short -> byte.

Why can typecasting be dangerous?

Why can typecasting be dangerous? Some conversions are not defined, such as char to int. You might permanently change the value of the variable. You might temporarily lose part of the data – such as truncating a float when typecasting to an int.

What is casting process and its types?

Traditional techniques include lost-wax casting (which may be further divided into centrifugal casting, and vacuum assist direct pour casting), plaster mold casting and sand casting. The modern casting process is subdivided into two main categories: expendable and non-expendable casting.
