Converting temperature program

Alright so I'm having trouble creating this program, basically I need to prompt the user to enter a 1 or 2 if 1, you run a convert from Fahrenheit to celsius, or if the user presses 2, the program runs celsius to fahrenheit. Here's what I have so far:

Code :

---

import java.util.Scanner;
 
public class TemperatureConverter{
   public static void main(String[] args){
      Scanner console = new Scanner(System.in);
 
      System.out.println("Please press 1 to convert Fahrenheit to Celsius, or 2 to convert Celsius to Fahrenheit");
      int choice = console.nextInt();
                if (choice == 1){
	  	   ftoc();	  
	  	 }
	  	 else if (choice == 2){
	  	   ctof();
	  	  }
 
      System.out.println("What is the temperature?");
      double temperature = console.nextDouble();
 
 
      System.out.println("Your converted temperature is ");
   }
 
   //converts fahrenheit to celsius
   public static double ftoc (double degreesF){
      double degreesC = 5.0/9.0 * (degreesF - 32);
      return degreesC;
   }
 
   //converts celsius to fahrenheit
   public static double ctof (double degreesC){
      double degreesF = 9.0/5.0 * (degreesC + 32);
      return degreesF;
   }
 
}

I'm having trouble with what I need to do after the user puts a 1 or a 2 idk how I should go about if the user presses 1 then run this method, but if the user presses 2 run this method. It keeps giving me a bunch of errors saying that it's a variable, but I'm not assigning a variable, I'm calling the method to run that. I'm so confused :confused:

your ftoc and ctof methods require you to pass a double as a parameter.

Something like this:

Code :

---

ftoc(5.0);

---

You still need to get a number to convert from the user (use the nextDouble() method in Scanner).

Huh? :confused: Do you mean instead of nextInt make it nextDouble? What do I put inside the parenthesis then?

try this, just a re-arrange and helloworlds edit.

Code :

---

import java.util.Scanner;
 
public class TemperatureConverter{
   public static void main(String[] args){
      Scanner console = new Scanner(System.in);
 
      System.out.println("Please press 1 to convert Fahrenheit to Celsius, or 2 to convert Celsius to Fahrenheit");
      int choice = console.nextInt();
 
 
      System.out.println("What is the temperature?");
      double temperature = console.nextDouble();
      double t = 0.0;
      if (choice == 1){
	  	  t = ftoc(temperature);	  
      }
      else if (choice == 2){
	  	  t = ctof(temperature);
      }
 
      System.out.println("Your converted temperature is " + t );
   }
 
   //converts fahrenheit to celsius
   public static double ftoc (double degreesF){
      double degreesC = 5.0/9.0 * (degreesF - 32);
      return degreesC;
   }
 
   //converts celsius to fahrenheit
   public static double ctof (double degreesC){
      double degreesF = 9.0/5.0 * (degreesC + 32);
      return degreesF;
   }
 
}
