java - 将静态二维字符串数组转换为 HashMap

Question

将二维字符串数组转换为 HashMap 的最简单方法是什么？

举个例子:

final String[][] sheetMap = { /* XSD Name,  XSL Sheet Name */
                              {"FileHeader", "FileHeader"}, 
                              {"AccountRecord", "AccountRecord"}, 
                              {"DriverCardRecord", "DriverCardRecord"}, 
                              {"AssetCardRecord", "AssetCardRecord"},
                              {"SiteCardRecord", "SiteCardRecord"}
                            };

这很可能是从文件中加载的，而且会更大。

Answer 1

final Map<String, String> map = new HashMap<String, String>(sheetMap.length);
for (String[] mapping : sheetMap)
{
    map.put(mapping[0], mapping[1]);
}
