add the static keyword in the place of ? if appropriate. public class test { int count; public ? void main(string[] args) { ... } public ? int getcount() { return count; } public ? int factorial(int n) { int result
The common property shared by all objects can be referred to by the static variable (which is not unique for each object).
What does static keyword means?The Java programming language's static keyword designates a member as belonging to the type itself, as opposed to an instance of that type. This indicates that since the static member is shared by all instances of the class, we'll only construct one instance of it.
The common characteristic shared by all objects, which is not specific to each object, can be referred to by the static variable, for instance, the name of the employer for employees, the name of the college for students, etc. When the class is loaded, the static variable only receives one memory allocation in the class area.
Java uses static keywords frequently because of its effective memory management system. The general rule is that you must first build an instance or object of a class in order to access variables or methods contained within it.
The complete question is:
Add the static keyword in the place of ? if appropriate.
public class Test {
int count;
public ? void main(String[] args) {

return count;
}
public ? int factorial(int n) {
int result = 1;
for (int i = 1; i <= n; i++)
result *= i;

An exception that the memory management unit raises whenever a process accesses a memory page without making the necessary preparations is known as a page fault in computing (also known as a hard fault or PF). The virtual address space of the process must be expanded with a mapping before the page can be accessed.
A backing store, like a disk, may also need to be loaded in order to access the actual page contents. The operating system's kernel handles the exception by making the necessary page accessible in the physical memory or preventing an illegal memory access after the MMU detects the page fault.
Any operating system that makes use of virtual memory, such as Windows, macOS, and the Linux kernel, is prone to valid page faults and requires them in order to give programs more memory.

ge changed its performance appraisal method from a force ranking system and now utilizes an effective method that involves which of the following?
GE changed its performance appraisal method from a force ranking system and now utilizes an effective method that involves forced distribution.
Many businesses use the forced distribution method of employee performance evaluation. We also refer to it as the bell-curve rating, stacked ranking, or the forced distribution approach. Employers use it as a scoring system to assess their workforce. Each employee must be evaluated by managers, who typically place them in one of three categories: poor, good, or excellent. More categories might exist.
Even though forced distribution is very common among businesses, HR professionals have mixed feelings about it. Human Resources is abbreviated as HR. Its detractors claim that it might lead to unhealthy rivalry or unwelcome competition among staff. Additionally, it may result in low morale and animosity. Furthermore, some personnel cannot be placed inside one of the three groups, according to opponents.

the diagram shows a typical use of nat and pat, in which a router (r1) translates addresses from packets flowing between the enterprise network on the left and the internet on the right. consider a packet sent by pc1 toward the web server, while the packet passes the lan to the left of router r1. which of the following statements are true about this packet and the network in general? (select three answers.)
A network and a single host on that network can be uniquely identified by the Destination Address, a conventional 32-bit IP address.
What is a destination IP address?The gadget is uniquely identified internationally by its internet address, or IP address. Both addresses are required for a network packet to reach its destination.A device is identified by its physical address, also known as its media access control, or MAC, address, to other devices connected to the same local network. Destination ip: An IP address that can react to ICMP packets from the VPN Monitor and is available over the VPN tunnel.The IP address is connected to the domain name. Links refer to the location where the IP address information is stored but do not themselves contain any information. It is useful to consider IP addresses as the real code and domain names as a shorthand for that code.True statements :
Normally, the source and destination IP addresses would be public addresses.The destination address of the packet is regarded as an internal global address.Both the source and destination IP addresses are public since the packet is presently travelling across the public Internet. Before forwarding the packet inside the Enterprise, R1 converts the destination IP address to PC1's internal local IP address.Learn more about IP address refer to ;

a controller that uses dependency injection to get a class that inherits the dbcontext class is to ef.
A controller that uses dependency injection to get a class that inherits the DbContext class is idempotent to EF.
Querying from a database and grouping together changes that will be written back to the store as a unit are both possible using a DbContext instance, which combines the Unit of Work and Repository patterns. ObjectContext and DbContext are conceptually related.
DbContext is typically used in conjunction with a derived type that has DbSetTEntity> attributes for the model's root entities. When a derived class instance is created, these sets are automatically initialized. Applying the SuppressDbSetInitializationAttribute property to either the entire derived context class or specific attributes on the class will change this behavior. There are various approaches to specify the Entity Data Model supporting the context. The DbSetTEntity> is used when applying the Code First method.

Which of the following items is the least important to consider when designing an access control system? A. Risk. B. Threat. C. Vulnerability. D. Annual loss expectancy.
The correct response is d. Annual loss expectancy. The projected financial loss that can be anticipated for an asset due to a risk over the course of a year is known as the annualized loss expectation (ALE).
The annualized loss expectancy can now be calculated by adding the monetary loss from a single incident (SLE) and the likelihood of an incident (ARO) (ALE). The ALE is calculated as follows and represents the annual average loss over a period of several years for a specific asset under threat: ARO x SLE equals ALE. The annual financial impact of a specific risk to the organization is estimated by ALE. This aids in determining how much money the company should spend on countermeasures to lessen the impact or chance of an incidence.The security expert must take into account potential weaknesses before designing any kind of access control system because these give rise to threats. Threats must also be taken into account because they increase hazards. Risk is the likelihood that the vulnerability will be used against you. Answer D is erroneous as it relates to the risk analysis formula.
