Mere ek dost ne mujhse poocha ki ye software engineering mein design patterns hai kya hote hai? Use maine kaafi simple tarike se samjhane ki koshish ki aur aapko bhi karta hu is chote se video mein jaldi se, video acchi lage to bas like kar dena.
Software engineering mein design patterns kya hote hai?design patterns software engineering mein commonly use kiye jaane wale repeatable solutions hote hain jo specific problems ko solve karne ke liye design kiye gaye hote hain. Ye patterns, developers ko common design problems mein guidance dete hain aur unhe ek structured approach provide karte hain.
In patterns ko usually teen main categories mein divide kiya jata hai:
Creational Patterns:
- Ye patterns object creation ke liye use hote hain. Jaise ki:
- Singleton: Sirf ek instance ko allow karne wala pattern.
- Factory Method: Object creation ko subclasses ke upar dependant banata hai.
Structural Patterns:
- Ye patterns object composition aur relationships ke liye use hote hain. Jaise ki:
- Adapter: Ek interface ko doosre interface se connect karne ka pattern.
- Decorator: Object ke behavior ko dinamically change karne ka pattern.
Behavioral Patterns:
- Ye patterns object interaction aur responsibility distribution ko define karte hain. Jaise ki:
- Observer: Objects ke beech ke changes ko track karne ka pattern.
- Strategy: Alag-alag algorithms ko encapsulate karne ka pattern.
In patterns ke alawa bhi aur patterns hote hain jo specific problems ke liye design kiye gaye hote hain. Har pattern ke apne specific use cases aur advantages hote hain, aur unka use karke developers efficient aur maintainable code likh sakte hain.
