Properties类

Properties类

Properties 类是 Hashtable 的子类，该对象用于处理属性文件

//Properties:常用来处理配置文件。key和value都是String类型
    public static void main(String[] args) throws IOException {
        FileInputStream fileInputStream = null;
        try {   //快捷键ctrl alt T
            Properties pros = new Properties();
            fileInputStream = new FileInputStream("jdbc.properties");
            pros.load(fileInputStream);//加载流对应的文件

            String name = pros.getProperty("name");
            String password = pros.getProperty("password");

            System.out.println(name+"====="+password);
        } catch (IOException e) {
            e.printStackTrace();
        }finally {
            if (fileInputStream!=null){
                try {
                    fileInputStream.close();
                }catch (IOException e){
                    e.printStackTrace();
                }
            }
        }
    }
