There are a few interfaces called as Marker Interfaces(FlagInterfaces)<wbr /> which do not have any methods in them.<br />
<br />
Serializable is one such interface. what it does is instructs teh compiler &amp;&nbsp;then teh run time environment to perform a certain operation. In case of serializable all the vraiables , objects are serialized(convereted to bytes) &amp;&nbsp;can be used by ObjectInout/output streams for their purposes.<br />
<br />
Remote is another marker interface in the java.rmi package which qualifies the interface as a remote object.<br />

Flag Interface?

Java is a platform-independent, object-oriented programming language and run-time environment, designed to have as few implementation dependencies as possible such that developers can write one set of code across all platforms using libraries. Most devices will not run Java natively, and require a run-time component to be installed in order to execute a Java program.
