What is an accessor method?An instance method that acquires or sets the value of a property of an object is called an accessor method.A mutator method in computer science is a technique for managing modifications to a variable. They're also frequently referred to as setter methods. A getter, which returns the value of the private member variable, is frequently used in conjunction with a setter.Accessor methods in Java return the contents of a private variable. Without having direct access to the variable itself, this allows other classes to access the value that is stored in the variable. Accessor methods have a return type that is the same as the type of the variable they are accessing and no arguments.Learn more about accessor method refer to :

true or false: the following statement might plausibly appear as a functional requirement: the system shall compute a student's gpa by dividing the total grade points for the prior semester by the total credits for that semester, omitting from those totals any courses assigned a grade that does not affect the gpa.
Removing any courses with grades that have no impact on GPA from those totals. This assertion is accurate.
A functional requirement is what?The functionality of a system or one of its subsystems is specified in a functional requirement document. The kind of program, anticipated users, and system type where the software is used are further factors. Functional system requirements should also explicitly specify the system services in detail.

About Time-Complexity:
Your program is functional, but it runs too slowly. Or perhaps your neat little piece of code is running just fine, but slower than that other, longer one. In computer science, the Big-O notation is frequently used to describe the efficiency or complexity of an algorithm. Practically speaking, it serves as a gauge to determine whether your function is effective and whether it needs to be improved.
As you continue your education, time-complexity will play a bigger role in your development environment. You'll eventually be able to evaluate your software and determine which programs fit into which time complexity categories (constant, linear, quadratic, exponential, logarithmic). To better understand how Time-Complexity works in your code and in real life, we'll be breaking down the fundamentals in this guide.
O(N²) — Quadratic Time:
An algorithm with quadratic time complexity has performance that is squarely correlated with the size of the input data set (think of Linear, but squared). This temporal complexity will appear in our applications anytime we nest over numerous iterations in the data sets.
Let's look at the cards again. How to eliminate all the cards with the same number if, for example, you chose the first card in the deck.

How to solve if the timeout period elapsed prior to obtaining a connection from the pool. this may have occurred because all pooled connections were in use and max pool size was reached?
Explanation:
If the timeout period elapsed prior to obtaining a connection from the connection pool, it may mean that all pooled connections are in use and the maximum pool size has been reached. This can occur when there are too many concurrent connections to the database and the connection pool is unable to accommodate them.
There are several ways to resolve this issue:
Increase the maximum pool size: By increasing the maximum pool size, you can allow the connection pool to accommodate more concurrent connections. However, this may not be a feasible solution if the database is already experiencing high levels of traffic.
Optimize database queries: If the connection pool is being overwhelmed by inefficient database queries, optimizing the queries can help reduce the number of concurrent connections and allow the connection pool to function more effectively.
Implement connection pooling: If the application is not already using connection pooling, implementing it can help reduce the number of concurrent connections and improve the performance of the database.
Use a load balancer: If the database is experiencing high levels of traffic, using a load balancer can help distribute the load across multiple database instances, reducing the number of concurrent connections and improving performance.
Use a cache: Implementing a cache can help reduce the load on the database by storing frequently accessed data in memory, reducing the need for database queries.
By taking one or more of these actions, you can help resolve the issue of the timeout period elapsed prior to obtaining a connection from the connection pool.

A sensor is used at traffic lights to identify the presence of automobiles. Either a closed loop or an open loop can exist.
How do open and closed loops differ?
An open-loop control system, commonly referred to as a non-feedback system, solely bases its actions on the input; the control action is unaffected by the output. A closed-loop control system, commonly referred to by the term review system, examines the power capacity and modifies it to produce the desired condition.
What distinguishes an open loop from a closed loop?

What is systemctl?Systemctl is a command line utility used to control the state of services and daemons running on Linux systems. It can be used to start, stop, restart, enable, disable and check the status of services and daemons. It is the primary tool for managing services and daemons on Linux systems and is included with most major distributions. Systemctl is part of the systemd project, which provides a suite of tools for managing systems and services.
This command will show you which target is currently set as the default. If the target being returned is not multi-user.target, then you can use the command systemctl set-default multi-user.target to set it as the default. Once the default has been set, you can then use the command systemctl isolate multi-user.target to ensure that the system boots to the multi-user.target unit each time it is rebooted.
