for语句练习 阶乘

4的阶乘：4！=1*2*3*4

public class g {

    /**
     * @param args
     */
    public static void main(String[] args) {
 
   int n = 4;

        // 4！=1*2*3*4
        long l = 1;// 阶乘计算结果
        for (int i = 1; i <= n; i++)

        {
            l = l * i;
            {    System.out.println("l=" + l);}
        }

        System.out.println(n + "!=" + l);
}
