Question

I was wondering, can I group properties in my property file? This is content of my property file:

dbpassword=password
database=localhost
dbuser=mkyong

I want to add to dbpassword more then 1 password. Can I do it?

Add more than one separated by a separator and then split the read property. — Averroes, Sep 14 '12 at 11:20

Typically you'd do this with some sort of manual "nesting":

foo.dbpassword=password
foo.database=localhost
foo.dbuser=mkyong

bar.dbpassword=...
...

But to be honest, by the time you've got a hierarchy, you should at least consider using a more naturally-hierarchical file format - XML springs to mind.

With a simple Properties file, you'd have to use

either more than one key (eg pwd1, pwd2, etc. or mybd1.pwd, mybd2.pwd, etc.)
a value with a separator and many paswords (eg "mypass1 anotherpass")

Supposing you use the second scheme, you may be interested by String splitting to extract the different passwords.

In property file,

dbpassword=password1,password2

In java file,

String[] dbpasswords = properties.getProperty("dbpassword").split(",");

You should reference in Multiple values in java.util.Properties

You can store your properties as an XML file. It will be smth like:

<props>
    <database>
        <name>name1</name>
        <dbpass>pass1</dbpass>
        <dbuser>user1</dbuser>
    </database>
    <database>
        <name>name2</name>
        <dbpass>pass2</dbpass>
        <dbuser>user2</dbuser>
    </database>
</props>
