Question

我有以下代码：

String base64 = "data:image/png;base64,iVBORw0KGgoAAAANSUh.....";
base64 = base64.substring(22, base64.length());

问题是我有20个if-check，我检查addSetting.Property。现在回答问题：

重构这些if语句的最佳和最有效的方法是什么？

Answer 1

你可以使用adSetting.STUFF_AS_STRING - ＆gt;获得20x2数组。 rc.RoleName mapping。

然后在for循环中遍历数组
