I just need some help working out this Java code! I can list the instructions below:
Modify the CountSpaces program so that contains a String that holds your favorite inspirational quote. Pass the quote to the calculateSpaces method and return the number of spaces to be displayed in the main method.
We're given this to start however I have been struggling as there are two classes and it's been confusing me. Thanks so much for any help! All good and God Bless!
public class CountSpaces
{
public static void main(String[] args)
{
// write your code here
}
public static int calculateSpaces(String inString)
{
// write your code here
}
}
Answer:
public class CountSpaces
{
public static void main(String[] args)
{
String quote = "The concept of infinity is meaningless inside of an insane human mind.";
int nrSpaces = calculateSpaces(quote);
System.out.println("Nr spaces in your quote is " + nrSpaces);
}
public static int calculateSpaces(String inString)
{
int count = 0;
for (int i = 0; i < inString.length(); i++) {
if (inString.charAt(i) == ' ') {
count++;
}
}
return count;
}
}
Explanation:
In this example there is only one class, and since all methods are static the true concept of the class is not even being used.
Q.No.2. A study of the effect of smoking on sleep patterns is conducted. The measure observed is the time, in minutes, that it takes to fall asleep. These data are obtained: [3] Smokers:69.3 56.0 22.1 47.6 53.2 48.1 52.7 34.4 60.2 43.8 23.2 13.8 Non Smokers: 28.6 25.1 26.4 34.9 28.8 28.4 38.5 30.2 30.6 31.8 41.6 21.1 36.0 37.9 13.9
Answer:
(a) [tex]\bar x_1 = 43.7[/tex] [tex]\bar x_2 = 30.25[/tex]
(b) [tex]\sigma_1 = 16.93[/tex] [tex]\sigma_2 = 7.14[/tex]
(c) Smoking increases the time to fall asleep
Explanation:
Solving (a): The sample mean of each group
Mean is calculated as:
[tex]\bar x = \frac{\sum x}{n}[/tex]
So, we have:
Smokers
[tex]n_1= 12[/tex] and
[tex]\bar x_1 = \frac{69.3 +56.0+ 22.1 +47.6+ 53.2+ 48.1+ 52.7 +34.4+ 60.2 +43.8 +23.2 +13.8}{12}[/tex]
[tex]\bar x_1 = \frac{524.4}{12}[/tex]
[tex]\bar x_1 = 43.7[/tex]
Non Smokers
[tex]n_2 = 15[/tex] and
[tex]\bar x = \frac{28.6 +25.1 +26.4 +34.9 +28.8 +28.4 +38.5 +30.2 +30.6 +31.8 +41.6 +21.1 +36.0 +37.9 +13.9}{15}[/tex]
[tex]\bar x_2 = \frac{453.8}{15}[/tex]
[tex]\bar x_2 = 30.25[/tex]
Solving (b): The standard deviation of each group
This is calculated as:
[tex]\sigma = \sqrt{\frac{\sum(x - \bar x)^2}{n-1}}[/tex]
For smokers
[tex]n_1= 12[/tex]
So:
[tex]\sigma_1 = \sqrt{\frac{(69.3 -43.7)^2+(56.0-43.7)^2+..........+(13.8-43.7)^2}{12-1}}[/tex]
[tex]\sigma_1 = \sqrt{\frac{3152.04}{11}}[/tex]
[tex]\sigma_1 = \sqrt{286.5491}[/tex]
[tex]\sigma_1 = 16.93[/tex]
For non-smokers
[tex]n_2 = 15[/tex]
So:
[tex]\sigma_2 = \sqrt{\frac{(28.6 -30.25)^2+(25.1 -30.25)^2+..........+(13.9 -30.25)^2}{15-1}}[/tex]
[tex]\sigma_2 = \sqrt{\frac{713.2575}{14}}[/tex]
[tex]\sigma_2 = \sqrt{50.9469}[/tex]
[tex]\sigma_2 = 7.14[/tex]
Solving (c): Impact of smoking on time to sleep
In (b), we have:
[tex]\sigma_1 = 16.93[/tex] --- smokers
[tex]\sigma_2 = 7.14[/tex] --- non-smokers
Smokers have larger standard deviation (i.e. large variability) than non-smokers. This means that smokers require more time to fall asleep.

an_is a sepuence of precise instructions which result in a solution
Answer:
algorithm.
Explanation:
An algorithm can be defined as a standard formula or procedures which comprises of set of finite steps or instructions for solving a problem on a computer. The time complexity is a measure of the amount of time required by an algorithm to run till its completion of the task with respect to the length of the input.
Furthermore, the processing symbols and their functions used in developing an algorithm are oval (start or stop), diamond (decision-making), circle (on-page connector), parallelogram (input and output), rectangle (calculation), arrow (flow or direction) and pentagon (off-page connector).
Some of the characteristics of an algorithm include the following;
I. An algorithm can be written using pseudocode. A pseudocode refers to the description of the steps contained in an algorithm using a plain or natural language.
II. An algorithm can be visualized using flowcharts. A flowchart can be defined as a graphical representation of an algorithm for a process or workflow.
In conclusion, an algorithm is a sequence of precise instructions which result in a solution for solving problems using a computer system.
A ____ is an icon that does not directly represent a file, folder or application but serves as a link to it?
Answer:
Shortcut
Explanation:
A file can be defined as a computer resource that avails end users the ability to store or record data as a single unit on a computer storage device.
Generally, all files are identified by a name, icon, size, and type (format) such as audio, image, video, document, system, text, etc.
Furthermore, files are organized or arranged in directories. These directories are paths that describes the location wherein a file is stored on a computer system.
A software can be defined as a set of executable instructions (codes) or collection of data that is used typically to instruct a computer on how to perform a specific task and solve a particular problem. Thus, it's a computer program or application that comprises of sets of code for performing specific tasks on the system.
In Computer science, it's possible to create a shortcut in several directories (locations) on a computer, so as to reference a file, folder or software application and serve as an executable link.
Hence, a shortcut is an icon that does not directly represent a file, folder or application but serves as a link to it.
Additionally, deleting the shortcut of a data file, folder or software application would not permanently delete or uninstall the main data file respectively.
Suppose a large group of people in a room were all born in the same year. Consider the following three algorithms, which are each intended to identify the people in the room who have the earliest birthday based on just the month and day. For example, a person born on February 10 is considered to have an earlier birthday than a person born on March 5. Which of the three algorithms will identify the correct people?
I. All the people in the room stand up. All standing people form pairs where possible, leaving at most one person not part of a pair. For each pair, the person with the earlier birthday remains standing, while the other person in the pair sits down. If there is a tie, both people sit down. Any individual not part of a pair remains standing. Continue doing this until only one person remains standing. That person has the earliest birthday.
II. All the people in the room stand up. All standing people form pairs with another standing person that they have not previously been paired with where possible, leaving at most one person not part of a pair. For each pair, the person with the earlier birthday remains standing, while the other person in the pair sits down. If there is a tie, both people in the pair remain standing. Any individual not part of a pair remains standing. Continue doing this until only one person remains standing or all persons standing have the same birthday. Anyone still standing has the earliest birthday.
III. Beginning with the number 1, ask if anyone was born on that day of any month. Continue with the numbers 2, 3, and so on until a positive response is received. If only one person responds, that person has the earliest birthday. If more than one person responds, determine which person was born in the earliest month, and that person or those persons have the earliest birthday.
Answer:
II is correct.
Explanation:
Algorithm is a computer program which solves complex problems within minutes. The algorithms has different variants which are used according to user demand. In the given scenario the choice no II is correct. All standing people can form a pair with another standing person and the person standing in the last will have the earliest birthday.
