To form a noun from an adjective in English you just put an article before the adjective and you are done.
Examples
red
=
the red
good
=
the good
nice
=
the nice
fair =
the fair
In German it's actually the same. The only difference
is that there are three articles that can be used.
Example 1
rot* =
das Rote
der Rote
die Rote
die Roten
Example 2
gut =
das Gute
der Gute
die Gute
die Guten
Example 3
schön =
das Schöne
der Schöne
die Schöne
die Schönen
Example 4
gerecht =
das Gerechte
der Gerechte
die Gerechte
die Gerechten
(* Ok, we admit it there
is an ending. But don't kill the messenger! You know that
in the old times the messenger of bad news was often killed.
Luckily we live in modern times!
The declension of substantivated adjectives is not different
from the declension of "normal" adjectives.
It just depends on
a) gender and number of the noun (substantivated adjective!)
c) is there an article or a possessive pronoun
Let's
look at some examples
first example
Die Guten kommen in den
Himmel, die Bösen kommen überall hin. = The good go to
heaven the bad get everywhere.
declension is Nominative
gut
good
die Guten (masculine/feminine,
plural)
the good
The table we need is the one with the definite article
before the adjective:

second example
Der Glanz des Schönen erhebt
die Seele. = The shine of the beautiful heightens
the soul.
declension is Genitive
schön
beautiful
das Schöne (neutral,
singular)
the beautiful
Isn't it romantic? Now we have a little contradiction
to the romance - the analysis. The table we need is
the same as before.
third example
Die Ehrlichen waren in
der Minderheit. = The honest were in minority.
declension is Nominative
ehrlich
honest
die Ehrlichen (nominative,
masculine/feminine, plural)
the honest
The table we need is again the same as before to receive
the ending we need.
fourth example
Einige Glückliche haben
gewonnen. = Some lucky (ones) have won.
declension is Nominative
glücklich
happy, lucky
die Glücklichen (nominative,
masculine/feminine, plural)
the lucky (ones)
In this case we have an indefinite article. Therefore
we need the table with the indefinite articles.
