在网页上运行Java应用程序 [英] Running a Java application on a webpage

问题描述

我编写了一个我想在网页中运行的Java应用程序。如何做到这一点？

I have written a Java application that I would like to run inside of a web page. How do I do this?

代码如下：

Code is below:

class Permutations {
    static long factorial(int num){
            long factorial = 1;
            for (int forBlockvar = num; forBlockvar > 1; forBlockvar--) {
                    factorial = factorial * forBlockvar;
            }
            return factorial;
    }

    public static void main(String[] args){
            long FactNmR;
            int n = 10;
            int num = n;
            int r = 4;
            int nMr = n - r;
            long FactN = factorial(num);
            if (nMr <= 1){
                    FactNmR = 1;
            }
            else  {
                    num = nMr;
                    FactNmR = factorial(num);
            }
            long permutations = FactN;
            permutations = permutations / FactNmR;
            System.out.println(permutations);
   }
}

推荐答案

有几种方法可以用java做到这一点。

There are several way to do this with java.

一种方法是使用Java Servlet来完成。

One way is to do it with Java Servlet.

您需要一个带有指向Servlet的动作的html表单（一个扩展的Java类）
