30 How To Create Custom Marker Interface In Java Pdf Class There are four main in built marker interfaces in jdk. here is the quick summary of them. serializability of a class is enabled by the class implementing the java.io.serializable interface. object’s clone() method may be called. In java, a marker interface is an empty interface that has no fields or methods. it is used just to mark or tag a class to tell java or other programs something special about that class. these interfaces do not have any methods inside but act as metadata to provide information about the class.
Marker Interface In Java Coding Ninjas List of best collection of 50 java interface interview questions with answers. practice interface interview programming questions in java. Marker interfaces have two advantages over marker annotations. first and foremost, marker interfaces define a type that is implemented by instances of the marked class; marker annotations do not. A marker interface is an interface that doesn’t have any methods or constants inside it. it provides run time type information about objects, so the compiler and jvm have additional information about the object. In this section, we will discuss about marker interface in java, its uses, built in (serializable, cloneable, and remote interfaces) and custom marker interface with examples.
