The java.io.Writer.flush method flushes the stream. If the stream has saved any characters from the various write() methods in a buffer, write them immediately to their intended destination. Then, if that destination is another...
No any method is required to implement. Here is the declaration of Serializable Interface. public abstract interface java.io.Serializable { }
The ObjectInputStream class supports the reading of objects from input streams.
The Reader/Writer class hierarchy is character-oriented, and the InputStream/OutputStream class hierarchy is byte-oriented. Most of the functionality available for byte streams is also provided for character streams. The methods for character streams generally accept...
The marker interface pattern is a design pattern in computer science, used with languages that provide run-time type information about objects. It provides a means to associate metadata with a class where the language...

Java Uses primitive types such as byte,short,int,long,float,double,char and boolean, to hold the basic data type supported by the language. And thus,the primitive types are not part of the Object hierarchy, and they do not...
Platform independence means that we can write and compile the Java code in one platform (eg Windows) and can execute the class in any other supported platform eg (Linux, Solaris, etc).
