Java Why Is Casting Bad at Max Ruth blog

Java Why Is Casting Bad. Up casting usually costs virtually nothing, (when you change the reference type to a parent class of the object). Generics are essentially sugared casting, yes you should ideally prefer them to casting but not. If you're going to have a collection of objects that have similar. Not because it is inherently bad but because you shouldn’t need to. It means you're probably missing a common interface somewhere. Narrowing type casting is unsafe because data loss might happen due to the lower data type’s smaller range of permitted values. Your compiler can't tell you the type of object at compile time, it can't tell you if your cast will lead to a class cast exception. Generally you shouldn’t use casting very often. Casting in c++ is problematic but in java it isn't. In this foundational tutorial, we’ve explored upcasting, downcasting, how to use them and how these concepts can help you take advantage of polymorphism.
