对*.ini文件的增删改查

Posted 2021-01-11 chengxuzhijia

文件的格式有很多种 *.ini 一般是带一个齿轮的配置文件，这个文件的操作有专门的类库进行处理不行自己硬编码      ini4j.jar

这个jar包专门封装了处理*.ini文件的方法。

1 public interface IParaManager {
2     public int getKey(String section, String key, CInt value);
3     public int getkey(String section, String key, CString value);
4     public int getkey(String section, String key, CDouble value);
5     public Map<String, String> getGeys(String section);
6     public int setKey(String section, String key, String value);

8 }
