The data frame first_south is created using first_south = (titanic['Pclass']==1) & (titanic['Embarked']=='S')
<h3>How to create the data frame?</h3>
To do this, we make the following assumptions:
- The pandas module has been loaded as pd
- The dataset has also been loaded as titanic
When pclass column is 1.
This is represented as:
titanic['pclass']==1
When the passenger boards from Southampton.
This is represented as:
titanic['Embarked']=='S'
So, we have:
first_south = (titanic['Pclass']==1) & (titanic['Embarked']=='S')

Hope this helps
Thank you for being the rare question where you actually provide what language you want your answer in; I approve, and encourage this.
In Java, the following will work.
I made it a bit more versatile to work with others numbers, other than 99, if you so please (if not, just hardcode the 99 in yourself).
// Example list - fill this with numbers yourself.
ArrayList<Integer> nums = new ArrayList<>();
int n = 99;
int count = (int)nums.stream().filter(i -> i == n).count();
System.out.println(n + " occurences.");
Could be anything?

Answer:
- import java.util.Arrays;
- import java.util.Scanner;
-
- public class Main {
- public static void main(String[] args) {
- Scanner input = new Scanner(System.in);
- double distances [] = new double[7];
-
- for(int i=0; i < distances.length; i++){
- System.out.print("Input running distance for day " + (i+1) + ": ");
- distances[i] = input.nextDouble();
- }
-
- System.out.println(Arrays.toString(distances));
- }
- }
Explanation:
The solution code is written in Java.
Firstly, create a Scanner object to get user input for running distance (Line 6). Next, declare a distances array and set the array size to 7 because we intend to use this array to hold running distance for 7 days per week.
Next, use the for loop that run for 7 times to repeatedly prompt user to input running distance for each day and store each value to the array distances (Line 9 -12).
At last, display the array to console terminal (Line 14).
