Génération de codes
// Generate constructor
Alt+Insert → Constructor
// Generate getters/setters
Alt+Insert → Getter and Setter
// Generate toString()
Alt+Insert → toString()
// Generate equals() and hashCode()
Alt+Insert → equals() and hashCode()
// Generate test methods

Meilleures pratiques
Qualité du code
- Utiliser des outils d'inspection et d'analyse des codes
- Suivre les normes et conventions de codage
- Écrire des tests unitaires complets
- Utiliser des noms significatifs de variables et de méthodes
- Garder les méthodes petites et ciblées
- Utiliser des structures de données appropriées
- Éviter l'optimisation prématurée
- Code de profil pour identifier les goulets d'étranglement
- Utiliser l'initialisation paresseuse le cas échéant
- Minimiser la création d'objets en boucles
Stratégies de débogage
- Utiliser des points d'arrêt conditionnels
- Évaluer les expressions pendant le débogage
- Utiliser l'exploitation forestière pour le débogage de la production
- Étape systématiquement
- Examiner les états variables et les piles d'appel
Recommandations pour le plugin
