Which of the following statements is false? Question 4 options: By convention class names begin with an uppercase letter, and me
amm1812

Answer:

Instance variables can be declared anywhere inside a class.

Although there isn't any rule to declare instance variables before methods, and they can be declared anywhere in the class, they cannot be declared inside method definitions of class.

///////////////////////////////////////////////////////////////////////////////////////////////////////////

<em>By convention class names begin with an uppercase letter, and method and variable names begin with a lowercase letter.</em> - True.

<em>Instance variables exist before methods are called on an object, while the methods are executing and after the methods complete execution.</em> - True.

<em>A class normally contains one or more methods that manipulate the instance variables that belong to particular objects of the class.</em> - True

Tell what an array is and list two scenarios in which modeling data as a Java array (vs. another data type) would make sense.
OlgaM077 [116]

Answer:

The definition including its context of this discussion is outlined in the following clarification portion.

Explanation:

  • An array seems to be a storage research method to collect a set number of constant weight. Whenever the array was indeed generated, the length including its array has been determined. Its period is set after development.
  • Depending mostly on array description, the array may contain data structures and even some objects in something like a class. For primitive data types, the individual values become located at contiguous locations throughout the store.

Scenario:

  • If we're to preserve a summary, we could use the appropriate array size.
  • An individual can however preserve an object list.

Recall that the name of a transport-layer packet is segment and that the name of a link-layer packet is frame. What is the name
AlladinOne [14]

Answer:

A network-layer packet is a data gram. A router forwards a packet based on the packet's IP (layer 3) address. A link-layer switch forwards a packet based on the packet's MAC (layer 2) address.

Explanation:

When the end system receives the unstructured bit stream from the physical wire, each layer removes the header information applicable to it until the application receives the data.

1. An application, such as an email program, creates data that will be sent by an end user, such as an email message. The Application layer places a header (encapsulation) field that contains information such as screen size and fonts, and passes the data to the Presentation layer.

2. The Presentation layer places layer 6 header information. For example, the text in the message might be converted to ASCII. The Presentation layer will then pass the new data to the Session layer (layer 5).

3. The Session layer follows the same process by adding layer 5 header information, such as information that the Session layer will manage the data flow, and passes this data to the Transport layer (layer 4).

4. The Transport layer places layer 4 information, such as an acknowledgement that the segment was received in the header, and passes it to the Network layer (layer 3).

5. The Network layer places layer 3 header information, such as the source and destination address so the Network layer can determine the best delivery path for the packets, and passes this data to the Data Link layer (layer 2).

6. The Data Link layer places layer 2 header and trailer information, such as a Frame Check Sequence (FCS) to ensure that the information is not corrupt, and passes this new data to the Physical layer (layer 1) for transmission across the media.

7. The bit stream is then transmitted as ones and zeros on the Physical layer. It is at this point that the Physical layer ensures bit synchronisation. Bit synchronisation will ensure the end user data is assembled in the correct order it was sent.

8. Steps 1 through 7 occur in reverse order on the destination device. Device B collects the raw bits from the physical wire and passes them up the

Data Link layer. The Data Link layer removes the headers and trailers and passes the remaining information to the Network layer and so forth until data is received by the Application layer. Eventually, Device B will receive an email notification displaying a message to indicate that a new email message has been received.
