java - Scanner cannot be used when declared, sc cannot be resolved -

the problem i'm having program scanner, i've used many times in program won't run right. error in public static double getcandlecost() , public static int getshippingtype() methods. under int shippingtype = sc.nextint(); , double candlecost = sc.nextdouble(); both "sc cannot resolved" , in main class did declare it.

  import java.util.scanner;   import java.text.decimalformat;   public  class candel {    public static void main(string[] args) {      scanner sc = new scanner(system.in);      double candlecost, shippingcost;     int shippingtype;      candlecost = getcandlecost();     shippingtype = getshippingtype();     shippingcost = getshippingcost(candlecost, shippingtype);     output(candlecost, shippingcost);   }  public static double getcandlecost() {        boolean done = false;     do{         try         {             system.out.print("enter cost of candle order ");             double candlecost = sc.nextdouble();             done = true;             return candlecost;         }   catch (inputmismatchexception e)         {             system.out.println("error, enter dollar amount greater 0");          }     } while (!done);     return 0; }  public static int getshippingtype() {     system.out.println("enter type of shipping: ");     system.out.println("1> priority <overnight>");     system.out.println("2> express  <2 business days>");     system.out.println("3> standard <3 7 business days>");     system.out.println("enter type number: ");     int shippingtype = sc.nextint();     if(shippingtype == 1){}         else if(shippingtype == 2){}             else if(shippingtype == 3){}     return shippingtype;  } public static double getshippingcost(double candlecost, int shippingtype) {          switch(shippingtype)         {         case 1:             candlecost = 16.95 + candlecost;             break;         case 2:             candlecost = 13.95 + candlecost;             break;         case 3:             if (candlecost > 100.00){                 candlecost = candlecost;             }             else{                 candlecost = 7.95 + candlecost;             }             break;             }         return candlecost;  }    public static void output(double candlecost, double shippingcost) {     decimalformat twodigits = new decimalformat("$#,000.00");     system.out.println("the candle cost of " + twodigits.format(candlecost) + " shipping costs of "              + shippingcost + " equals " + twodigits.format(candlecost + shippingcost));  }  } 

your scanner out of scope. since have declared in main() method, method can access it. scanner needs static well. write instead:

public  class candel {     static scanner sc = new scanner(system.in);      public static void main(string[] args) {         ...     }     ... }
