The idea
A limited group of masculine nouns keeps its base form only in the nominative singular and adds -(e)n in the other cases. Similar-looking nouns may follow mixed patterns and must remain separate.
The basic contrast has two forms, not four: der Student versus den Studenten, dem Studenten and des Studenten. The plural is also Studenten in every case; articles show its function. The n therefore belongs to the noun and is not a dative ending that can be added to any word.
Many members denote people or animals. Masculines ending in -e are commonly weak: der Junge, der Kunde, der Kollege, der Löwe. Foreign-derived endings such as -ant, -ent, -ist, -oge and -at are also common: Demonstrant, Präsident, Journalist, Biologe, Soldat. Several frequent words must be learnt lexically: Mensch, Herr, Held, Bär, Nachbar.
The exact ending depends on the base. Junge forms Jungen; Student forms Studenten; Herr shortens its oblique singular to Herrn and uses Herren in the plural. Meaning alone does not identify the entire class, so learn each noun with its nominative and plural and confirm its pattern.
Name is not a regular weak masculine noun. It forms den Namen and dem Namen, but its genitive is des Namens. This is a mixed pattern because -(e)n combines with a genitive s. Herz is neuter and also special: das Herz, dem Herzen, des Herzens. Putting them in the same row as Student would conceal real differences.
To solve a sentence, first identify gender and case from the determiner, then ask whether the noun belongs to the weak class. If it does and the form is not nominative singular, add -(e)n. Finally check for Herr or a mixed pattern before writing the form.

How it sounds
- Der Kunde wartet vor dem Büro.Nominative singular: Kunde keeps its dictionary form.
- Die Mitarbeiter sprechen mit dem Kunden.The weak dative singular adds -n.
- Der Bericht des Journalisten fehlt.Journalist adds -en in the genitive as well.
- Wir helfen Herrn Becker.Herr forms Herrn in the oblique singular cases.

Your turn
Two or three, to check that the bit above landed.
Ich danke dem ___. (Kollege)
Kollegen — Kollege is weak masculine and the dative singular adds -n: dem Kollegen.
Wir sehen den ___ vor dem Rathaus. (Präsident)
Präsidenten — Präsident belongs to the -ent group, and its accusative singular is Präsidenten.
Die Entwicklung dieses ___ war schwierig. (Gedanke)
Gedankens — Gedanke follows the mixed pattern: Gedanken in the accusative and dative, but Gedankens in the genitive.
When it doesn't hold
What breaks the rule, said out loud. Hiding it is what makes you feel cheated in the exam.
- The mixed ones also add an -s in the genitive, and there are only a few.des Namens, des Herzens
- Herr takes -n in the singular and -en in the plural, and is the only one like that.dem Herrn, den Herren
- In speech many people drop this -n, but in writing it is still a mistake.Ich sehe den Junge.
What your own language pushes you to say
Wrong Ich sehe den Junge.
Right Ich sehe den Jungen.
English nouns only ever change for plural and possession, so the idea of an ending that appears in three cases out of four has nothing to attach to. This group is small enough to learn as a list.
