In this project, you will create a Java program that asks a customer at a clothing store for his waist measurement. Based on his response, you will tell him his pant size is small, medium, or large. You will write this code twice, once using a switch-case statement and once using nested if statements.
( PLEASE HELP, THIS IS MAKING ACTUAL CODE THEY NEVER TAUGHT ME HOW TO CODE SO I DONT KNOW HOW TO, THE CODE DOESN'T NEED TO BE RIGHT IT JUST NEEDS TO LOOK LIKE IT )

import java.util.Scanner;

public class WaistSize {

public static void main(String[] args) {
Scanner input = new Scanner(System.in);

System.out.println("What is the measurement of your waist in inches?");
int waistSize = input.nextInt();

String sizeGuideA = sizeGuide1(waistSize);
String sizeGuideB = sizeGuide2(waistSize);

System.out.println("Nested If Statements return: " + sizeGuideA);
System.out.println("Switch-Case Statements return: " + sizeGuideB);

}
public static String sizeGuide1(int n) {
String size = "null";

if(n <= 25) {
return size = "Extra Small";
}

if(n > 25 && n <= 28) {
return size = "Small";
}

if(n > 28 && n <= 30) {
return size = "Medium";
}

if(n > 30 && n <= 32) {
return size = "Large";
}
else {
return "Error";
}
}

public static String sizeGuide2(int n) {
String size = "null";

switch(n) {

What are some ways that a sequence can go wrong? How could you solve any communication issues? Do you think this can happen with a computer program?
