You may use a format as follows:
file.ini
-----------
driver=namedriver
db=namedb
.....
this is the classical format of a properties file.
Than you just open a stream to that file and use the load function of a java.util.
Propeties object to load the whole file.
than do something like:
name=prop.getProperty("db");
driver=prop.getProperty("driver");
Example:
java.io.FileInputStream is = null;
java.util.Properties p = new java.util.Properties();
String propertiesFilename = "settings.ini";
try {
is = new java.io.FileInputStream(propertiesFilename);
p.clear(); // not realy necessary
p.load(is);
//System.out.println("pr:" + Prop.properties.toString());
} catch (java.io.IOException ioex) {
System.out.println("Can't read the settings file");
} catch (Exception ex) {
ex.printStackTrace();
} finally {
if (is != null) {
try {
is.close();
} catch (java.io.IOException ioex1) {
ioex1.printStackTrace();
}
is = null;
}
}
than
even you use an: Enumeration e = p.keys();
or simply get a value of a property as I have shown you above.
