Edhesive is an online learning platform that offers computer science courses, including coding, for high school students. One of the courses they offer is AP Computer Science A, which covers topics such as programming in Java, object-oriented programming, and data structures and algorithms.
As part of this course, students work on a variety of coding projects and assignments, including the 6.5 Code Practice.
The 6.5 Code Practice assignment is a programming challenge that requires students to write a Java program that calculates and displays the area and perimeter of a rectangle. The program should prompt the user to enter the length and width of the rectangle, calculate the area and perimeter using the formulae A = length * width and P = 2 * (length + width), and then display the results to the user.
To complete this assignment, students should start by creating a new Java class and defining a main method. They should then use the Scanner class to prompt the user for input and store the values in variables. After that, they can use the formulae to calculate the area and perimeter and store the results in variables. Finally, they should use the System.out.println() method to display the results to the user.

In Java I’m having trouble with variables. When I try to call a variable from my while loop it says, “finger cannot be resolved to a variable.” The error is on line 49.
You're declaring variable finger inside your while loop so it only exists inside your while loop. You're then trying to use your finger variable outside your while loop, which is impossible because finger only exists inside your while loop.
Try declaring total at the beginning of your program, adding finger to total before you break from your while loop and then adding randNum to your total at the end.
To better understand why you can't use finger outside your while loop, look up "java scope". This will explain why you can only use variable in the regions they're declared in.

Exercise 2. 4. 8: Greetings and Salutations5 points
Write a class called Salutations that prints various greetings and salutations.
The class should have one instance variable, a String called name to represent the person to whom the salutations are directed.
The class should have the following methods
A constructor that takes a String to initialize name with
public void addressLetter()
public void signLetter()
public void addressMemo()
public void signMemo()
addressLetter should print "Dear name", where name is replaced by the value of the instance variable name
signLetter() should print
"Sincerely,
name"
where name is replaced by the value of the instance variable name
addressMemo should print "To whom it may concern"
signMemo should print
"Best,
name
where name is replaced by the value of the instance variable name
Below is the implementation of the "Salutations" class in Java that meets the provided requirements:
public class Salutations {
private String name;
public Salutations(String name) {
this.name = name;
}
public void addressLetter() {
System.out.println("Dear " + name + ",");
}
public void signLetter() {
System.out.println("Sincerely,\n" + name);
}
public void addressMemo() {
System.out.println("To whom it may concern");
}
public void signMemo() {
System.out.println("Best,\n" + name);
}
public static void main(String[] args) {
Salutations salutations = new Salutations("John Doe");
salutations.addressLetter();
salutations.signLetter();
salutations.addressMemo();
salutations.signMemo();
}
}
Below is the implementation of the "Salutations" class in Java that meets the provided requirements:
java
Copy code
public class Salutations {
private String name;
public Salutations(String name) {
this.name = name;
}
public void addressLetter() {
System.out.println("Dear " + name + ",");
}
public void signLetter() {
System.out.println("Sincerely,\n" + name);
}
public void addressMemo() {
System.out.println("To whom it may concern");
}
public void signMemo() {
System.out.println("Best,\n" + name);
}
public static void main(String[] args) {
Salutations salutations = new Salutations("John Doe");
salutations.addressLetter();
salutations.signLetter();
salutations.addressMemo();
salutations.signMemo();
}
}
In the above class, we have an instance variable called "name" of type String, which represents the person to whom the salutations are directed. The class has a constructor that takes a String argument to initialize the "name" variable.
The class also includes the following methods as specified:
The "addressLetter" method prints "Dear name", where "name" is the value of the instance variable.
The "signLetter" method prints "Sincerely," on one line and then prints the "name" on the next line.
The "addressMemo" method prints "To whom it may concern".
The "signMemo" method prints "Best," on one line and then prints the "name" on the next line.
To test the functionality of the "Salutations" class, a "main" method is included that creates an instance of the class with a sample name "John Doe". It then calls the different methods to demonstrate the expected output.
Executing the main method will result in the following output:
Dear John Doe,
Sincerely,
John Doe
To whom it may concern
Best,
John Doe
Each method performs its respective task as described, utilizing the instance variable "name" in the output statements.

find a recurrence relation for the number of regions created by n mutually intersecting circles on a piece of paper (no three circles have a common intersection point).
Assume that the plane is divided into rn regions by n circles. The next step is to add a new circle, C, which non-trivially intersects all of the previous n circles.
You can begin anywhere on C and circle C while crossing one of the other n circles twice. The arc of C from p0 to p1 splits one of the original rnregions into two smaller regions if p0 and p1 are two successive crossings. You repeat this 2n times, which results in a recurrence. Since rn+1=rn+some basic n function, you can pretty easily convert this expression into an expression for rn that is simply a sum. If you do it correctly, you can evaluate the summation in closed form to obtain the rn formula fairly quickly.
