I wrote the code below in Java with TextIO, I need the program to exit when I chose '3' but it still asks to enter the temp? also I need it to give the option at the end "Do you want another conversion Y/N" how to do incorporate this into the program?

import textio.TextIO;
/**
* A program that reads a value that is typed in by the
* user and computes and prints the conversion of that value.
*/
public class TempConvert {
public static void main (String[] args) {

 System.out.print("Enter 1 for Fahrenheit to Celsius \n"
                       + "Enter 2 for Celsius to Fahrenheit conversion \n"
   + "Enter 3 to exit");
          int operation = TextIO.getlnInt();
          
          System.out.print("Enter temperature : ");
          float temperature = TextIO.getlnFloat();
          
          float convertedTemperature = 0f;
          
          /*
           * Perform temperature conversion using switch statement in Java.
           */
          switch (operation) {
          
          //Fahrenheit to Celsius temperature conversion
          case 1:
                 convertedTemperature = ((temperature - 32) * 5) / 9;
                 System.out.println(temperature + " Fahrenheit " + " in Celsius = "
                              + convertedTemperature);
                 break;
                 
          //Celsius to Fahrenheit temperature conversion
          case 2:
                 convertedTemperature = (9 * temperature / 5) + 32;
                 System.out.println(temperature + " Celsius " + " in Fahrenheit = "
                              + convertedTemperature);
                 break;

 //case 3 to exit program
 case 3:
  System.out.println("\nProgram will now terminate. Goodbye!");
                 System.exit(0);

          default: // optional
                 System.out.println("Enterd temerature is Invalid");
                 break; // optional
          }
   }
}
