Because threads have some of the properties of processes, they are sometimes called lightweight processes. In a process, threads allow multiple executions of streams. This is why thread needs its own stack. An operating...
We need to implement java.io.Serializable interface which we are willing to write to a stream as an object. Example import java.io.Serializable; public class Employee implements Serializable { Integer empId; String empName; public Integer getEmpId()...
As many people have probably already given their Idea, interfaces can be used to enforce certain behaviors between classes that will not implement those behaviors the same way. So by implementing an interface you...
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...
If a thread attempts to execute a synchronized method or synchronized statement and is unable to acquire an object’s lock, it enters the waiting state until the lock becomes available.
The operating system’s task scheduler allocates execution time to multiple tasks. By quickly switching between executing tasks, it creates the impression that tasks execute sequentially.
