Return Values Tags with attributes id and scope (even if they are optional) are expected to return a value as a result of using the tags. Values can be “returned” in two ways: Print to the JspWriter stream If the attribute id is not given when using a tag, the tag prints the val...

In summary, while the bytecode representation for a constructor shows a return descriptor of V, it would be inaccurate to state that constructors in Java have a void return type. Instead, constructors in Java simply don’t have a return type. So, taking another look at our simple assignmen...
Moreover, we think that there are some more benefits that could be achieved by such an annotation. Nullable and NonNull annotations can be used by the major IDEs and by Kotlin to determine nullability. The Kotlin compiler even infers the types needed for params and return values in Java inter...
