Explanation:
please find the complete question in the attached file:
In the above-program code, a double constant variable "Pi" is defined that holds a value, in the next step, a class "Planet" is defined, in the class a default and parameter constructor that is defined that hold values.
In the next step, a get method is used that return value, that is "planet_name, radius, and volume".
In the next step, a method "maxRadius" is defined that accepts two-parameter and calculate the index value, in the main method class type array is defined, and use an array to hold value and defined "idx" to call "maxRadius" method and use print method to call get method.

In this exercise you will debug the code which has been provided in the starter file. The code is intended to take two strings, s1 and s2 followed by a whole number, n, as inputs from the user, then print a string made up of the first n letters of s1 and the last n letters of s2. Your job is to fix the errors in the code so it performs as expected (see the sample run for an example).
Sample run
Enter first string
sausage
Enter second string
races
Enter number of letters from each word
3
sauces
Note: you are not expected to make your code work when n is bigger than the length of either string.
1 import java.util.Scanner;
2
3 public class 02_14_Activity_one {
4 public static void main(String[] args) {
5
6 Scanner scan = Scanner(System.in);
7
8 //Get first string
9 System.out.println("Enter first string");
10 String s1 = nextLine(); 1
11
12 //Get second string
13 System.out.println("Enter second string");
14 String s2 = Scanner.nextLine();
15
16 //Get number of letters to use from each string
17 System.out.println("Enter number of letters from each word");
18 String n = scan.nextLine();
19
20 //Print start of first string and end of second string
21 System.out.println(s1.substring(1,n-1) + s2.substring(s1.length()-n));
22
23
24 }
Answer:
Here is the corrected program:
import java.util.Scanner; //to accept input from user
public class 02_14_Activity_one { //class name
public static void main(String[] args) { //start of main method
Scanner scan = new Scanner(System.in); //creates Scanner class object
System.out.println("Enter first string"); //prompts user to enter first string
String s1 = scan.nextLine(); //reads input string from user
System.out.println("Enter second string"); //prompts user to enter second string
String s2 = scan.nextLine(); //reads second input string from user
System.out.println("Enter number of letters from each word"); //enter n
int n = scan.nextInt(); //reads value of integer n from user
System.out.println(s1.substring(0,n) + s2.substring(s2.length() - n ));
} } //uses substring method to print a string made up of the first n letters of s1 and the last n letters of s2.
Explanation:
The errors were:
1.
Scanner scan = Scanner(System.in);
Here new keyword is missing to create object scan of Scanner class.
Corrected statement:
Scanner scan = new Scanner(System.in);
2.
String s1 = nextLine();
Here object scan is missing to call nextLine() method of class Scanner
Corrected statement:
String s1 = scan.nextLine();
3.
String s2 = Scanner.nextLine();
Here class is used instead of its object scan to access the method nextLine
Corrected statement:
String s2 = scan.nextLine();
4.
String n = scan.nextLine();
Here n is of type String but n is a whole number so it should be of type int. Also the method nextInt will be used to scan and accept an integer value
Corrected statement:
int n = scan.nextInt();
5.
System.out.println(s1.substring(1,n-1) + s2.substring(s1.length()-n));
This statement is also not correct
Corrected statement:
System.out.println(s1.substring(0,n) + s2.substring(s2.length() - n ));
This works as follows:
s1.substring(0,n) uses substring method to return a new string that is a substring of this s1. The substring begins at the 0th index of s1 and extends to the character at index n.
s2.substring(s2.length() - n ) uses substring method to return a new string that is a substring of this s2. The substring then uses length() method to get the length of s2 and subtracts integer n from it and thus returns the last n characters of s2.

Write a method called min that takes three integers as parameters and returns the smallest of the three values, such that a call of min(3, -2, 7) would return -2, and a call of min(19, 27, 6) would return 6. Use Math.min to write your solution.
Answer:
public class Main
{
public static void main(String[] args) {
System.out.println(min(3, -2, 7));
}
public static int min(int n1, int n2, int n3){
int smallest = Math.min(Math.min(n1, n2), n3);
return smallest;
}
}
Explanation:
*The code is in Java.
Create a method named min that takes three parameters, n1, n2, and n3
Inside the method:
Call the method Math.min() to find the smallest among n1 and n2. Then, pass the result of this method to Math.min() again with n3 to find the min among three of them and return it. Note that Math.min() returns the smallest number among two parameters.
In the main:
Call the method with parameters given in the example and print the result
Methods are named program statements that are executed when called/invoked.
The method in Python, where comments are used to explain each line is as follows:
#This defines the method
def mmin(a,b,c):
#This calculates the smallest of the three values using math.min
minNum = min(a,b,c)
#This prints the smallest value
return minNum

To create a public key signature, you would use the ______ key.
Answer:
To create a public key signature, you would use the _private_ key.
Explanation:
To create a public key signature, a private key is essential to enable authorization.
A private key uses one key to make data unreadable by intruders and for the data to be accessed the same key would be needed to do so.
The login details and some important credentials to access user data contains both the user's public key data and private key data. Both private key and public key are two keys that work together to accomplish security goals.
The public key uses different keys to make data readable and unreadable.
The public key is important to verify authorization to access encrypted data by making sure the access authorization came from someone who has the private key. In other words, it's a system put in place to cross-check the holder of the private key by providing the public key of the encrypted data that needed to be accessed. Though, it depends on the key used to encrypt the data as data encrypted with a public key would require a private key for the data to be readable.

Custom function definitions:________.
A. Must be written before they are called by another part of your program
B. Must declare a name for the function
C. Must include information regarding any arguments (if any) that will be passed to the function
D. all of the above
Answer:
D. all of the above
Explanation:
A option is correct and function definition must be written before they are called by another part of your program. But in languages such as C++ you can write the prototype of the function before it is called anywhere in the program and later write the complete function implementation. I will give an example in Python:
def addition(a,b): #this is the definition of function addition
c = a + b
return c
print(addition(1,3)) #this is where the function is called
B option is correct and function definition must declare a name for the function. If you see the above given function, its name is declared as addition
C option is correct and function definition must include information regarding any arguments (if any) that will be passed to the function. In the above given example the arguments are a and b. If we define the above function in C++ it becomes: int addition( int a, int b)
This gives information that the two variables a and b that are parameters of the function addition are of type int so they can hold integer values only.
Hence option D is the correct answer. All of the above options are correct.
Works in the public domain have copyright that are expired or abandoned true or false
Answer:
False
Explanation:
Only one of the two are true. Works in the public domain have a copyright that has expired only. E.g. Works of classical music artist, are almost always expired, in accorance with American Copyright law. Abandoning a copyright doesn't do anything because so long the copyright has remained unexpired, the copyright remains. Thats why it can take decades for a new movie in a series to release, like "IT" by Stephen King. The copyright hasn't expired but rather was 'abandoned'. Before "IT" 2017 was relasesed, the copyright was abandoned.

All the queries begin with the Select command. The column and the table names are clearly noted in the instructions. This command can also execute projects and join several operations in combination or individually.
Assume you are using an array-based queue and have just instantiated a queue of capacity 10. You enqueue 5 elements, dequeue 5 elements, and then enqueue 1 more element. Which index of the internal array elements holds the value of that last element you enqueued
Answer:
The answer is "5".
Explanation:
In the queue based-array, it follows the FIFO method, and in the question, it is declared that a queue has a capacity of 10 elements, and insert the 5 elements in the queue and after inserting it enqueue 5 elements and at the last, it inserts an element 1 more element on the queue and indexing of array always start from 0, that's why its last element index value is 5.
