In this activity, you are asked to create an application for educational institutes to assist the student services and administrations to manage students' grades and monitor their performance (grades are integers and out of 100).

Each institute in each semester has a different number of programs, a different number of classes/courses, and a different number of students in each class; therefore, your application will ask the user to insert the number of the programs along with the name of the programs, the number of classes in each program, and the number of students in each class from the user.

Student services would like to monitor the performance of each class separately by having the average grade of the students in each class and the highest and the lowest grades in each class/course. Besides, in each program, the courses/classes with the best and worst performances will be announced.

As another parameter to be considered, student services would like to make a comparison between all the available programs; however, not only the number of courses in each program is different the weight of each course that is represented as the number of units or credit hours are different; therefore, the number of units for each course would be another user input.
To calculate the average grades in each program/department, the given formula below will be used:

Average Grade in Each Program = (Sum(Credit Hour * Course Average Grade))/The total number of Credit Hours in Each Program

The credit hours range of the different courses is from 1 credit hour to 5 credit hours which represents the importance and the weights of each course. Please, take into consideration the wrong input from the user such as negative numbers, zero, and numbers more than 5.

You need to make sure the least amount of memory will be used by this application.
Your code must have a very clean structure, separated and determined functions, and must have brief comments explaining each section of your code.

Explain how Java code gets executed under the hood.

IntelliJ uses the Java compiler to compile our code into a different format called Java bytecode. This Java code is platform independent and that means it can run on Windows Mac Linux or any operating systems that has a Java runtime environment. Java applications are portable or platform independent. Java was developed by James Gosling in 1995 at Sun Microsystems which was later acquired by Oracle in 2010. Java has close to 9 million developers worldwide currently about 3 billion mobile phones run Java as well as 120 million TV sets and every blu-ray player. Average salary of a Java developer is just over $ 100,000 per year in the US. This course is the first part of my complete four-part Java series. Each part is about three to four hours long so it can easily complete it in a day or two. The first part will give you a solid foundation on how to start programming in Java in the second part we 'll talk about object oriented programming which is a style of programming use in most if not all Java applications. The third part will talk about core Java API is or application programming interfaces.

Once you learn all this I 'm gon na give you a project you 're gon na build a mortgage calculator on your own so make sure to pay great attention to all the materials. Make sure to use most of them in this project are you ready now let 's jump in and get started in this tutorial we're gon na talk about variables in Java we use variables to temporarily store data. In the next tutorial we're going to talk about various types in Java. We have two categories of types we have primitive types and non primitive types or reference types for storing complex objects. All these types are for storing whole numbers that do n't have a decimal point. In one bite we can store values from 128 to 127. In Java whenever you deal with a large number like this you can use an underscore to separate every three digits just like how we use a comma in our documents to make our numbers more readable. With integers we can store values up to two billion but let 's say the number of times this video has been watched is three billion so I had a three here now we have a red line that indicates an error.

For many of us, smartphones have become indispensable, but they have also come under fire
for their impact on the way we think and behave, especially among children. Two of the largest
investors in Apple Inc. are urging the iPhone maker to take action against smartphone addiction
among children over growing concerns about the negative effects of technology. An open letter
to Apple on January 6, 2018 from New York-based JANA Partners and the California State
Teachers’ Retirement System (CalSTRS) stated that the firm must do more to help children
fight smartphone addiction. These two shareholders together control about $2 billion in Apple
stock. The investors’ letter urged Apple to offer tools to prevent smartphone addiction and to
provide more parental options for monitoring children’s smartphone usage. The iOS operating
system for Apple smartphones and tablets already has limited parental controls for restricting

apps, features such as location sharing, and access to certain types of content. The investors
felt Apple needs to do more—for example, enable parents to specify the age of the user of the
phone during setup, establish limits on screen time, select hours of the day the phone can be
used, and block social media services.
The average American teenager who uses a smartphone receives his or her first phone at age
10 and spends over 4.5 hours a day on it (excluding texting and talking). Seventy-eight percent
of teens check their phones at least hourly and 50 percent report feeling “addicted” to their
phones. The investors’ letter cited a number of studies on the negative effects of heavy
smartphone and social media use on the mental and physical health of children whose brains
are still developing. These range from distractions in the classroom to a higher risk of suicide
and depression. A recent survey of over 2,300 teachers by them Center on Media and Child
Health and the University of Alberta found that 67 percent of the teachers reported that the
number of students who are negatively distracted by digital technologies in the classroom is
growing. Seventy-five percent of these teachers think students’ ability to focus on educational
tasks has decreased. Research by psychology professor Jean Twenge of San Diego State
University found that U.S. teenagers who spend 3 hours a day or more on electronic devices
are 35 percent more likely, and those who spend 5 hours, or more are 71 percent more likely,
to have a risk factor for suicide than those who spend less than 1 hour. This research also
showed that eighth-graders who are heavy users of social media have a 27 percent higher risk
of depression. Those who spend more than the average time playing sports, hanging out with
friends in person, or doing homework have a significantly lower risk. Additionally, teens who
spend 5 or more hours a day on electronic devices are 51 percent more likely to get less than 7
hours of sleep per night (versus the recommended 9).
Nicholas Carr, who has studied the impact of technology on business and culture, shares these
concerns. He has been highly critical of the Internet’s effect on cognition, and these cognitive
effects extend to smartphone use. Carr worries that excessive use of mobile devices diminishes
the capacity for concentration and contemplation. Carr recognizes that smartphones provide
many useful functions in a very handy form. However, this extraordinary usefulness gives them
too much influence on our attention, thinking, and behaviour. Smartphones shape our thoughts
in deep and complicated ways, and their effects persist even when we aren’t using the devices.
Research suggests that the intellect weakens as the brain grows dependent on the technology.
Carr points to the work of Adrian Ward, a cognitive psychologist and marketing professor at
the University of Texas at Austin, who for a decade has been studying how smartphones and
the Internet affect people’s thoughts and judgment. Ward has observed that using a smartphone,
or even hearing one ring or vibrate, produces distractions that make it harder to concentrate on
a difficult problem or job. Divided attention impedes reasoning and performance.
A study published in Applied Cognitive Psychology in April 2017 examined how smartphones
affected learning in a lecture class with 160 students at the University of Arkansas at
Monticello. It found that students who didn’t bring their phones to the classroom scored a full
letter-grade higher on a test of the material presented than those who brought their phones. It
didn’t matter whether students who brought their phones used them or not. A study of 91 U.K.
secondary schools, published in 2016 in the journal Labour Economics, found that when
schools ban smartphones, students’ examination scores go up substantially, and the weakest 
students benefit the most. Carr also observes that using smartphones extensively can be
detrimental to social skills and relationships. Connecting with “friends” electronically via
smartphones is not a substitute for genuine person-to-person relationships and face-to-face
conversations.
