jsp第一次作业

1.计算1~100素数之和

<%
        int sum1 = 0;
        for (int m = 2; m <= 100; m++) {
            int x = 0;
            for (int n = 2; n < m; n++) {
                if (m % n == 0) {
                    x++;
                }
            }
            if (x == 0) {
                sum1+= m;
            }
        }
    %>
    <%=sum1 %>

 

2.计算1~100偶数之和

<%
        int sum = 0;
    %>
    <%
        for (int a = 0; a < 101; a += 2) {
            sum += a;
        }
    %>
    <%=sum%><br>
