#stack

Har bir Thread runtime ma'lumotlar saqlash uchun o'z Stack xotirasiga ega bo'ladi. Stack xotiraning ma'lum hajmi bo'ladi. Agar Thread Stack xotirasiga sig'maydigan darajada ko'p elementlar bilan ishlashga harakat qilsa, StackOverflow xatoligini keltirib chiqaradi.

Java oqimlari turli operatsion tizimlarda turlicha belgilangan hajmlarga ega Stacklar bilan ishlaydi. Misol uchun:
Windows IA32 — 64 KB
Windows IA64 — 320 KB
Windows x64 — 128 KB
Linux IA32 — 128 KB
Linux IA64 — 1024 KB
Linux x64 — 256 KB
Solaris/SPARC — 512 KB

Undan tashqari JVM ning ichki oqimlari bor. Misol uchun garbage collector, code generation oqimlari. Bular uchun hamma platformalarda hajm 256 KB qilib belgilangan.

Stack hajmini o'zgartirish uchun -Xss tanlovidan foydalanish mumkin. Misol uchun:

java -Xss:512k MyApplication

Ishlayaptimi? Tegma!

Biror joyga ishga borganda avval yozilgan loyihaga qo'shilsangiz, biror ortiqcha kodga ko'zingiz tushsa, uning ortiqchaligiga 100% ishonsangiz ham avval comment yoki documentationni o'qing. Aks holda videodagi holat bo'lishi mumkin. ;)

#SAVOL

Object nima va Object yaratish usullari?

#JAVOB

Object bu qaysidir classdan olingan nusxa. Bitta class dan bir nechta object olsak bo'ladi.



Ob'ekt yaratish usullari.
Javadan object yaratishning bir nechta usuli bor.

By new key word - new kalit so'zi orqali.
By newInstance() metod - newInstance() metodi orqali.
By clone() metod - clone metodi orqali.
By deserialization - deserializatsiya orqali.
By factory method - factory usuli orqali.

Ko'proq new keyword ishlatiladi.

#SAVOL

OOP nima ?

#JAVOB

OOP - Object Oriented Programming ya'ni ob'ektga asoslangan dasturlash deb tarjima qilinadi. OOP bu qisqartmasi.

OOP bu Ob'ektga asoslanga dasturlash bo'lib dasturlash davomida asosan ob'yekt lardan foydalaniladi.

Code yozish uchun oson.
Yozilgan kodlarni tushunish , o'zgartirish oson.
Bitta yozilgan kodni qayta ishlatish mumkin.
Parallel dasturlashni imkonini beradi. Ya'ni loyihani qismlarga ajratib bir vaqtni o'zida qismlarni ishlash mumkin.
Xavsizlik tomonidan kuchliroq.
Vorislik, Polimorfizm , Inkapsulatsiya , Abstraksiya  tamoyillaridan foydalanish imkonini beradi.

Choosing the correct design pattern in software engineering is critical to practical problem-solving.
This post will try to simplify the process, helping you decide between patterns based on specific needs.
To select a pattern, we must first go through the problem identification. If the problem is related to:
🔸 Object Creation? → Creational Patterns
🔸 Object Assembly? → Structural Patterns
🔸 Object Interactions? → Behavioral Patterns
1. Singleton: Ensures only one instance exists.
2. Factory Method: Delegates object instantiation to subclasses.
3. Abstract Factory: Creates related object families without specifying their concrete classes.
4. Prototype: Clones objects for a prototypical instance.
5. Builder: Constructs complex objects step by step.
6. Adapter: Bridges incompatible interfaces.
7. Bridge: Separates abstraction from implementation.
8. Composite: Treats single and composite objects uniformly.
9. Decorator: Adds behaviors to objects dynamically.
10. Facade: Simplifies complex system interfaces.
11. Flyweight: Shares objects to reduce memory.
12. Proxy: Controls object access.
13. Observer: Notifies changes to multiple objects.
14. Strategy: Encapsulates interchangeable algorithms.
15. Command: Encapsulates a request as an object.
16. State: Changes object behavior with internal state.
17. Visitor: Adds operations to object structures without modifying them.
18. Memento: Captures and restores object states externally.
19. Iterator: Sequentially accesses elements of a collection.
20. Mediator: Centralizes complex communications.
21. Chain of Responsibility: Passes requests along a chain of handlers.
22. Template Method: Defines the skeleton of an algorithm.

Bugungi masalani ancha o'ylab o'tirdim boshida.

Keyin bir yaxshi yechim kelib qoldi))
