Answer:

within the Book class but needs to also be outside of any methods.

Explanation:

If Ben is creating an entire Book class then the instance variable needs to be within the Book class but needs to also be outside of any methods. If Ben places the variable inside a method it can only be used by that method and therefore becomes an instance variable of that method and not the class. By creating it inside the class and outside the methods it can be used every single time a Book object is created. Therefore, creating an instance variable of serialNumber every time.

Answer:

C. Set the Group Filed field on the Quote Template or Template Section records.

D. Set the New Quote Group field on each Product record with the associated group name.

Explanation:

There are two ways through administrator can organized into pre-defined groups on the output document and name of these pre-defined groups needs to be displayed above each group in the output to identify it.

Both of the ways are given in option "C" and "D".

1. We set the group field on the quote template to organize the groups in pre-defined order on the output.

2. We also set the New Quote Group field on each Product record with the associated group name to display the name on each group in the output to identify it.

Which of the following commands would instruct OSPF to advertise ONLY the 192.168.10.0/24 network in Area 0?

xz_007 [3.2K]

Answer:

First, you need to start the OSPF process by executing the command:

<em>Router (config)# router ospf {process-ID#}</em>

Then, you have to instruct the router to advertise the networks that are directly linked to it by entering this network command with the area ID number for that network:

Router (config-router)# network {192.168.10.0} {255.255.255.0} area {0}

Which of the following methods is a static method? The class in which the method is defined is given in parentheses following th

maw [93]

Answer:

C. sqrt(Math)

Explanation:

All but one of options A to E are is not a static method.

Only option C is a static method. The sqrt() is a static method of Math, that can always be used as Math.sqrt() is used;

The Math class defines all of its methods to be static. Invoking Math methods is done by using Math as a method rather than a variable of type Math; this means that sqrt(Math) doesn't rely on instance variables and don't need to be overridden, unlike others.

Lastly, sqrt(Math) is a static method because unlike other options, it is an utility method, and it is relevant to computations on primitive data types.

The purpose of the static method is in large part to offer a standard library of functions, and it doesn't need to be applied directly to an object.
