Java 读写Properties配置文件-代码摘要

Properties props = new Properties(); 
try{
//读取属性文件a.properties
InputStream in = new BufferedInputStream (new FileInputStream("a.properties"));
props.load(in); ///加载属性列表
//获取属性值
System.out.println(props.getProperty("name"));
//关闭流
in.close();

//保存属性到b.properties文件
FileOutputStream oFile = new FileOutputStream("b.properties", true);//true表示追加打开
//设置属性值
props.setProperty("name", "shelenty");
//保存属性，Comment为注释信息
props.store(oFile, "Comment");
//关闭流
oFile.close();
}
catch(Exception e){
System.out.println(e);
}
