```java
import.java.util.Scanner;
class jisuanqi
{
double add(double a,double b)
{return (a+b);}
double jian(double a,double b)
{return (a-b);}
double cheng(double a,double b)
{return (a*b);}
double chu(double a,double b)
{return (a/b)}
}
public class jisuan{
public static void main(String arag[])
{
jisuanqi js=new jisuanqi(a,b);
Scanner in=Scanner(System.in);
System.out,print("请输入第一个数据:");
Double a=in.nextDouble();
System.out.print("请输入第二个数据:");
Double b=in.nextDouble();
System.out.print("请输入运算符号 + - * / :");
char s=in.next().charAt(0);
int result;
switch(s)
{
case '+':
System.out.println(js.add(a,b)); break;
case '-':
System.out.println(js.jian(a,b));break;
case '*':
System.out.println(js.cheng(a,b));break;
case '/':
System.out.println(js.chu(a,b));break;
}
}
