代码如下：

public class Print {    public static void main(String[] args) {        for (int i = 1; i <=8 ; i++){//以为要输出八行所以我另i从1增到8            StringBuilder stringBuilder = new StringBuilder();            for (int  m = 1; m <= i; m++){                stringBuilder.append("*");                for (int l = 1; l <= i - 1;  l++){                    stringBuilder.append(".");                }            }            System.out.println(stringBuilder.toString());        }    }}
