Which of these methods are used to register a mouse motion listener?
- A.
addMouse()
- B.
addMouseListener()
- C.
AddMouseMotionListner()
- D.
EventMouseMotionListener()
Correct Answer
C. AddMouseMotionListner()Explanation
The correct answer is addMouseMotionListener(). This method is used to register a mouse motion listener in Java. It allows the program to detect and respond to mouse motion events, such as when the mouse is moved or dragged. By using this method, the program can add a listener that will be notified whenever there is a mouse motion event, and perform the desired actions accordingly.Rate this question:

What is a listener in context to event handling?
- A.
A listener is a variable that is notified when an event occurs.
- B.
A listener is a object that is notified when an event occurs.
- C.
A listener is a method that is notified when an event occurs.
- D.
None of the mentioned
Correct Answer
B. A listener is a object that is notified when an event occurs.Explanation
A listener is an object that is notified when an event occurs. This means that when a specific event takes place, the listener object is informed and can perform certain actions or execute specific code in response to that event. The listener acts as a callback mechanism, allowing the program to respond dynamically to events as they happen.Rate this question:

Which of these methods can be used to determine the type of event?
- A.
GetID()
- B.
GetSource()
- C.
GetEvent()
- D.
GetEventObject()
Correct Answer
A. GetID()Explanation
The method getID() can be used to determine the type of event. This is because the ID of an event can provide information about the type or category of the event. By calling the getID() method, we can retrieve the ID associated with the event and use it to identify the type of event that occurred.Rate this question:

In event handling, A listener is a object that is notified when an event occurs.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
In event handling, a listener is an object that is notified when an event occurs. This means that when an event, such as a button click or a key press, happens, the listener object is informed and can perform some action in response to that event. This allows for the separation of event handling logic from the rest of the program, making it easier to manage and maintain. Therefore, the given answer "True" is correct.Rate this question:

- A.
Button
- B.
ScrollButton
- C.
AbstractButton
- D.
None
Correct Answer
C. AbstractButtonExplanation
AbstractButton is the correct answer because it is a superclass for push button, checkboxes, and radio buttons. This means that push button, checkboxes, and radio buttons inherit properties and behaviors from the AbstractButton class. The AbstractButton class provides common functionality for these types of buttons, such as handling user interactions and displaying visual states. Therefore, AbstractButton serves as a higher-level class that encapsulates the shared functionality for these specific types of buttons.Rate this question:

- C.
Text/html
- D.
Html/text
Correct Answer
C. Text/htmlExplanation
The program uses the URL class to create a URL object with the specified URL "http://www.sanfoundry.com/javamcq". Then, it uses the openConnection() method of the URLConnection class to establish a connection to the URL. Finally, it uses the getContentType() method of the URLConnection class to retrieve the content type of the URL.

- A.
DatagramPacket
- B.
DatagramSocket
- C.
Only DatagramSocket
- D.
Both A & B
Correct Answer
D. Both A & BExplanation
Both the DatagramPacket and DatagramSocket classes are necessary to implement datagrams. The DatagramPacket class represents a datagram packet, which is essentially a container for a message that can be sent over a network. The DatagramSocket class, on the other hand, is responsible for creating a socket that can send and receive datagram packets. Therefore, to implement datagrams, both classes are required.Rate this question:

None of the above
Correct Answer
C. Public Socket accept()Explanation
The correct answer is "public Socket accept()". This method is commonly used in the ServerSocket class to accept incoming client connections. It waits until a client connection is made and returns a Socket object representing that connection. This allows the server to communicate with the client using the returned Socket object. The other methods mentioned, getOutputStream() and close(), are not commonly used in the ServerSocket class.Rate this question:

Correct Answer
C. Ip.getHostName(), ip.getHostAddress()Explanation
The correct answer is "ip.getHostName(), ip.getHostAddress()". This is because the code is trying to print the host name and IP address of "www.google.com". The method "ip.getHostName()" returns the host name, which is "www.google.com", and the method "ip.getHostAddress()" returns the IP address associated with that host, which is the IP address of Google's server. Therefore, using both methods will give us both the host name and IP address of "www.google.com".Rate this question:

UDP you just send packets of data (datagrams) to some IP address on the network
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
The given statement is true. UDP (User Datagram Protocol) is a connectionless protocol in which data is sent in the form of packets called datagrams. These datagrams are sent to a specific IP address on the network without establishing a connection beforehand. Unlike TCP, UDP does not guarantee delivery or order of the packets, making it a faster but less reliable protocol for transmitting data.Rate this question:
