    map.put("${Wenyang}", "温飏");
    System.out.println(replaceAndGenerateWord(filepathString,
    destpathString,map));
    }

    }
    上面是代码。
    例如:班级学生人数不同要根据人数停止输出内容

好吧,代码确实太长 太。。。根据人数不同控制循环次数很简单:
for(int i = 0;i<班级个数;i++)
for(int j = 0;i<班级[i]人数;i++)
{
输出;
}

chentravelling 第二个循环是 吧i都改成j~~~~~~~打错~
