用java写个灰常简单的计算器类，但是后面不知道咋办了，怎么调用自己定义的方法？比如我分别定义加法，减法，乘法与除法四个方法
import java.util.Scanner;
public class Calculator
{
public double Add(double number1,double number2)
{
return number1+number2;
}
public double Subtract(double number1,double number2)
{
return number1-number2;
}
public double Multiple(double number1,double number2)
{
return number1*number2;
}
public double Divide(double number1,double number2)
{
return number1/number2;
}
public static void main(String[] args)
{
Scanner sc = new Scanner(System.in);
double number1 = sc.nextDouble();
double number2 = sc.nextDouble();
System.out.println();//这里怎么弄才可以？
}
}
当我再键盘上敲数字number1和number2后怎么把这两个数带入Add方法进行计算，然后输出相加的结果来？输出语句那里怎么弄？
