What do you mean by the DatagramSocket class?
What do you mean by the DatagramSocket class?
The Java DatagramSocket class represents a socket for sending and receiving datagram packets. It is a sending and receiving point for a packet delivery service where each packet is individually addressed and routed.
Which class has highest hierarchy in Java?
The Object class
The Object class, in the java. lang package, sits at the top of the class hierarchy tree. Every class is a descendant, direct or indirect, of the Object class. Every class you use or write inherits the instance methods of Object.
What protocol is used by the DatagramSocket class?
UDP
The DatagramSocket class implements packet-oriented, connectionless data communication. In Internet parlance, this is the User Datagram Protocol, commonly known as UDP (see RFC 768).
What is DatagramSocket explain it with example?
A datagram socket is the sending or receiving point for a packet delivery service. Each packet sent or received on a datagram socket is individually addressed and routed. Multiple packets sent from one machine to another may be routed differently, and may arrive in any order.
What is difference between socket and DatagramSocket?
A ServerSocket is for accepting incoming network connections on some stream protocol; e.g. TCP/IP. A datagram is bunch of information sent in a single logical packet.
Which constructor class is DatagramSocket?
Commonly used the constructor of DatagramSocket class
| Constructor | Description |
|---|---|
| DatagramSocket(int port, int,InetAddress)throws SockeEexception | It creates a datagram socket, bound to the specified port and InetAddress. |
Which class supersedes all classes in Java?
Object class
A: The Object class, which is stored in the java. lang package, is the ultimate superclass of all Java classes (except for Object ).
Which exception is thrown by DatagramSocket constructor?
DatagramSocket(int port, InetAddress address) throws SocketEeption: it creates a datagram socket and binds it with the specified port number and host address.
What are datagrams in Java?
A datagram is an independent, self-contained message sent over the network whose arrival, arrival time, and content are not guaranteed. The DatagramPacket and DatagramSocket classes in the java.net package implement system-independent datagram communication using UDP.
What is the best class of all classes in Java?
A: The Object class, which is stored in the java. lang package, is the ultimate superclass of all Java classes (except for Object ).
What class is super class for every class?
Object
The class named Object is the super class of every class in Java.
What is a datagramsocket class in Java?

A datagram socket is the sending or receiving point for a packet delivery service. Each packet sent or received on a datagram socket is individually addressed and routed.
What is a datagram socket?
A datagram socket is the sending or receiving point for a packet delivery service. Each packet sent or received on a datagram socket is individually addressed and routed. Multiple packets sent from one machine to another may be routed differently, and may arrive in any order.
Which protocol is used to implement the datagrams in Java?
The UDP protocol is used to implement the datagrams in Java. Java DatagramSocket class represents a connection-less socket for sending and receiving datagram packets. It is a mechanism used for transmitting datagram packets over network.` A datagram is basically an information but there is no guarantee of its content, arrival or arrival time.
How to close a socket in datagram in Java?
Then the method close () method of datagram socket class is called to close the socket. Then the method isClosed () method of datagram socket class is called to check if the socket is closed or not, and it returns a true if the socket is closed otherwise false.
