Software And Architecture

Introduction In Java, we have a type erasure problem where the runtime will not be able to preserve the type of the generic type that was intended and that will result in many times we having to pass the name of the class like Class<clz> ..  to provide the context information to perform the operations in generics. Type Erasure fun < T > getOnlyInts ( list : List < Any >): MutableList < T > { var result : MutableList < T > = mutableListOf () for ( item in list ) if ( item is T ) { result .add( item ) } return result } The above snippet of code illustrates the problem of type erasure where the type information for T is lost at runtime. this results in the type check failure in the line item is T Since the type data is erased , the runtime cannot figure out if it is performing the right type check. Hence the compilation fails. reiefied In Kotlin, we have the reified types which helps us to preserve the type information
