在类之外访问getProperty（）

Question

public static Properties defaultProps = new Properties();
      static {
        try {
            FileInputStream in = new FileInputStream("config.properties");
            defaultProps.load(in);
            in.close();
        } catch (Exception e) {
            e.printStackTrace();
        }
      }

      public static String getProperty(String database) {
        return defaultProps.getProperty(database);
      }

      public static void main(String[] args) {
          System.out.println(...key database?);
        // this is the part where I try to test if I can print the property 'database'
        // I also try to make it available to other classes, tried using public statics,
        }

这是我从属性文件config.properties中检索属性的代码。但是，我希望能够打印属性N（此处：database）并能够在其他类中使用属​​性N.

感谢您的帮助。

System.out.println(getProperty("database"));
