PreAPCS Exposure Java Exercises 05.01- 04 Date:1/15/14 Name: Anam Nawab Period: 4th 1. What Expo class method would you use to enter someone’s name? System.out.print("Enter name ===>> "); 2. Why is a prompt necessary for program input? Without a prompt, the user would just see the cursor flashing on the screen and have no idea what to enter. Chances are the user would not even know he/she is supposed to enter something. With the prompt, the user knows not only that he/she is supposed to enter something; he/she will also know what they are supposed to enter. 3. What does the enterString method do? The enterString method "reads" in an entire string of characters from the keyboard until the key is pressed. …show more content…
When you are about 70 miles from Dallas, shortly after you pass the town of Hillsboro the highway forks. It splits in two. You need to decide between going left which means you will take I35W (Interstate 35 West) to Fort Worth or going right which means you will take I35E (Interstate 35 East) to Dallas. 25. Explain Repetition. Another common application occurs when repetition is required. A grade book program needs to average grades for every student in a class of twenty-five students. A payroll program needs to process paychecks for many employees. Practically everything you can imagine is done multiple times. Nobody is interested in repeating program source code 500 times for some task that is to be performed 500 times. We want to create one program segment, and place this segment in some type of loop control structure that repeats 500 times. 26. What do Selection and Repetition control structures have in common? Both the selection control structure diagrams and the repetition diagram indicate a change of program flow occurring after some condition 27. What is the essence of understanding, and using, control structures? . Understanding conditional statements is the essence of understanding, and using, control structures. However, before we plunge into the syntax of the various conditional statements, you need to understand the relational operators that are used by Java in the conditional
met. In many ways this is similar to the “while” loop but instead of many times, a
Create 2 formulas, one that will calculate the last number in terms of the first number and a constant increase in rate as well as the total amount of numbers. The second formula will add ass of the resulting numbers from the first formula together after the last number is calculated.
The mean for the column “mean” is 3.56. It is very close to the parameter of interest but is not equal to it. You can calculate a confidence interval for the mean of the mean column, but a specific confidence interval would need to be provided. In that case, the confidence interval would be centered on 3.56, not 3.5.
It demonstrates the workflow behaviour of a system which describes the state of activities by showing the sequence of activities performed in different order. The diagram has branches and forks to describe conditions and parallel activities.
Traffic between both cities on interstate highway 45 is becoming more and more congested. Houston and Dallas have the most crowded cities in Texas. Businessmen and women travel 4 hours either to Houston or to Dallas during the week and the traffic can aggravate the driver from the hectic traffic. Texas Central also commented on the highway travel, “this trek could take upwards of 6.5 hours by 2035” (Texas Central). The Texas Central Railway will relieve the congestion of traffic on the roads to Houston and from
DALLAS, TEXAS. Dallas is on the Trinity River in the center of Dallas County in North Central Texas. It is crossed by Interstate highways 20, 30, 35, and 45. The city was founded by John Neely Bryan, who settled on the east bank of the Trinity near a natural ford in November 1841. Bryan had picked the best spot for a trading post to serve the population migrating into the region. The ford, at the intersection of two major Indian traces, provided the only good crossing point for miles. Two highways proposed by the Republic of Texas soon converged nearby. Unknown to Bryan, however, he had settled on land granted by the republic to the Texan Land and Emigration Company of St. Louis, headed by William S. Peters. Bryan eventually legalized his
This would mean programmers would have to edit their code every time they changed machines or added more memory (Lemley, 1999). Early computers had small amounts of RAM because storage technology was very expensive. Programmers had to store master copies of programs on a secondary storage system and pull pieces into RAM as needed. The process of deciding which pieces to pull and which parts of RAM to replace was called “overlaying” (Denning, 2012). “It was estimated that most programmers spent half to two-thirds of their time planning overlay sequences. A reliable method of automating it had potential to increase programmer productivity and reduce debugging by several fold” (Denning, 2012). Thus, the concept of virtual memory was born. This concept makes use of the computer’s hard drive when main memory runs out. However, the hard drive is significantly slower than RAM so we want to keep most of the program functioning in RAM thus specialized hardware and software is needed to give the illusion of unlimited available fast memory (Lemley, 1999). This hardware converts a “virtual” address to a physical address in memory. Aside from virtually increasing memory size, virtual memory also provided three additional benefits, “it isolated users from each other, it allowed dynamic relocation of program pieces within RAM, and it provided read – write access control to individual pieces” (Denning, 2012). It is for these
Each section indicates a (+) next to the process of preference for the given criteria.
The textbook that I choose to review from the library was Algebra 2 Common Core Volume 2 by Randall I. Charles, Basia Hall, and Dan Kennedy. This textbook offered an array of online resources that students and teachers can use to better the learning environment and experience—including online homework, activities, support, extra help, interactive work, exams, quizzes, reviews, and even personal progress checks. The book is aesthetically pleasing both externally and internally. The cover will easily reach out and connect with high school students. Also, the internal portion of the book is set up with colorful and bold attention grabbers. Along with those, the graphs and the small-animated people who range in genders, race, hair color, etc. all pop with colors. Each characterized person would change at the beginning of each new chapter and guide the student through. However, the book did not incorporate any individual with a disability.
Dallas has many major highways that cross through its land. These highways include 20, 30, 35, and 45. Interstate 35 actually extends all of the way up to Canada. The city is again on the Trinity River which it shares with another major city called Ft. Worth. Together the two cities make up the DFW area
The major Interstate Highway 90 is the primary way to get to Rapid City and it runs east and west of the city. There are other highways that contribute to roadway travel such as US 14, US 16, SD 79, and SD 44. There are seven Interstate interchanges throughout the city (Rapid City Chamber of Commerce, 2017).
I have attached a copy of my high school transcript with the courses and grades I have received throughout my last two years at Anacortes High School. This semester, I am taking ASB Leadership, Strength and Conditioning, Drama 3, Pre-Calc, AP Environmental Science, AP Literature and Composition, and Teacher's Aide for Mr. Thompson. My favorite classes I have taken at AHS are Honors World Religions and ASB Leadership. Honors World Religions is one of my favorite classes because it challenges you to think differently than any other class does. It not only talks about religious history, but also current world issues that involve religion. This class is said to be one of the hardest classes at AHS, but it is also the most interesting class I have
2. Describe the pattern of growth in the “Number of people told” column for both Scenario A and Scenario B.
Essential Answer: A function is a rule for taking each input value and producing exactly one output value.
In the writing interface, initially the focus will be on the start listening key. For example if the user has to enter the text ‘fh 1’, the user has to perform three tab operations to reach the key ‘s’. From there one right operation has to be performed to reach the key ‘f’. And to enter the letter ‘f’ in the text box, enter operation has to done. Therefore the user has to move his/her eyes three times in the up direction , once in right direction and then in bottom direction. Next the user has to enter the letter ‘h’. Since the focus is on the key ‘f’, the user perform two tab operations and two left operation and one bottom operation. Hence the user has to move his/her eyes twice in up direction and twice in left direction and then in bottom direction. Once a letter is entered, it is automatically displayed in the text box of the writing interface. Next to give a space, the use has to move his eyes thrice in up
