title: Nested if in while loop
body: <p>I am having some trouble getting my <code>while</code> loop to reiterate when executed. The if statements work as expected but the char value returned from the scanner isn't getting to my while loop. Anyone know what I did wrong or a better solution to my program?</p>
  
  <pre><code>package classWork;
  import java.util.Scanner;
  
  public class project_2 {
      public static void main(String[] args){
  
          Scanner input = new Scanner(System.in);
          int choice = 0;
          double celsius, fahrenheit, inches, centimeters;
          char doAgain = 'y';
  
          while (doAgain == 'y' || doAgain == 'Y')
          {
  
          System.out.print(" Main Menu \n 1. Celsius to Fahrenheit \n 2. Inches to Centimeters \n"
                  + "Please select either 1 or 2 \nThen press enter to continue");
          choice = input.nextInt();
  
          if (choice == 1)
          {
              System.out.println("This program will convert a celsius value into a fahrenheit one. \n");
  
              System.out.println("Please enter the tempature for conversion: ");
              celsius = input.nextInt();
  
              fahrenheit = 1.8 * celsius + 32.0;
  
              System.out.println(celsius + " degree(s) in celcius" + " is " + fahrenheit + 
                      " in fahrenheit. \n");
  
              System.out.println("Do you want to continue?\n: " +

              System.out.println("Please enter the length for conversion: ");
              inches = input.nextInt();
  
              centimeters = 2.54 * inches;
  
              System.out.println(inches + " inches is " + centimeters + " centimeters. \n");

          else
          {
              System.out.println("That is not a valid option. Please restart and try again");

              }
          }
