Is it possible to encrypt the connection password to the database that is inside a Java application?

Question

I have an application in Java and using the Postgresql database. To connect to the database I use this method:

    public static Connection getConnection() throws Exception {
        try {
            Class.forName("org.postgresql.Driver");
            Connection connection = DriverManager.getConnection(Constantes.URL_BD, Constantes.USUARIO_BD, Constantes.SENHA_BD);

            return connection;

        } catch (Exception e) {
            throw new Exception(e.getMessage());
        }
    }

I wonder if when passing the password to the getConnection() method of Drivermanager it may be encrypted in some way... whether using md5 or other hash.
