用JAVA语言在网页里实现加减乘除算法的源代码要怎么写吖？！

Answer 1

public class Excer{
public static void main(String args[])
{
Excer ex=new Excer();
int x=0;
int y=0;
ex.math(x,y);
}
void math(int x,int y){
MyMath mm = new MyMath();
System.out.println("x="+x+" ,y="+y);
System.out.println("x+y="+mm.plus(x,y));
System.out.println("x-y="+mm.minus(x,y));
System.out.println("x*y="+mm.multi(x,y));
System.out.println("x/y="+mm.div(x,y));
}
}
class MyMath
{
int plus(int a,int b)
{
return(a+b);
}
int minus(int a,int b)
{
return(a-b);
}
int multi(int a,int b)
{
return(a*b);
}
float div(int a,int b)
{
return ((float)a/b);
}
}
