prosedure_jsp类型的pro（int，int）方法不适用于参数（）

Question

this is my code

<%@ page import="static java.lang.System.out"%>

    void pro(int a, int b)
    {
        a = 1;
        b = 3;
        int luas;
        luas = a*b;

        out.print(a);
    }

    pro();
%>

and massage error is:

An error occurred at line: 16 in the jsp file: /prosedure.jsp
The method pro(int, int) in the type prosedure_jsp is not applicable for the arguments ()

Please help me with this issue.

Answer 1

You are trying to call a method that receives two input parameters ( int a and int b ) but you are not passing them anything.

You should put something like this:

<%
    pro(5,7);//5 and 7 are just an example
%>

Instead of what you have where you call pro .
