Method calling at run time

Hi All

package apple;

import java.io.IOException;
import java.util.Scanner;

/**

public class Apple {
   private double sample(){
       double total;
         int a=120;
         Scanner as=new Scanner(System.in);
         System.out.println("enter the value");
         double i=as.nextDouble();
         total=i*a;
         System.out.println("apple"+i+"kg"+" "+total);
         return total;
       
   }
   public double sample1(){
       int b=50;
       double total1;
       System.out.println("enter the value of ");
       Scanner bs=new Scanner(System.in);
       double j=bs.nextDouble();
       total1=j*b;
       System.out.println(+total1);
       return total1;
       }
   public void display(double total,double total1){
       double tot;
       tot=total+total1;
       System.out.println("total is"+tot);
   }
   
    
    public static void main(String[] args) throws IOException {
        
         
               Apple sam=new Apple();
               sam.sample();
               sam.sample1();
               [B]sam.display(total, total1);[/B]
         }
}

Here i am using sample and sample1 these two methods returns total and total1.While i run this piece of code throws an error.How can i get these two return values(total and total1) in to the main method and it is call to the display method to get a resultant output.Please let me know what kind of error it is...:-/

Thanks:)

what error is thrown?

[JamesCherrill]

total and total1 are local variables in methods sample and sample1 respectively. They do not exist outside those methods, and cannot be accessed from outside those methods.

public static void main(String[] args) throws IOException {
        
         
               Apple sam=new Apple();
               double a,b;
               a=sam.sample();
               b= sam.sample1();
               sam.display(a, b);
         }

its works

[stultuske]

well, either that, or

public static void main(String args[]){
Apple sam = new Apple();
sam.display(sam.sample(), sam.sample1());
}
