Java'da obyektlarni seriyalash uchun qanday standart interfeyslar yoki yondashuvlarni bilasiz?

Java'da obyektlarni seriyalash uchun bir nechta standart yondashuvlar mavjud:

• Serializable interfeysi — Java'da mavjud bo'lgan eng oddiy seriyalash usuli. Klass bu interfeysni amalga oshiradi va obyektlar bayt oqimiga seriyalash mumkin.

• Externalizable interfeysi — Serializableni kengaytiradi va writeExternal hamda readExternal metodlarini qo'llashni talab qiladi, bu seriyalash jarayonini qo'lda boshqarish uchun.

• Kutubxonalar, masalan, Jackson yoki Gson yordamida JSON formatiga seriyalash.

• Parcelable (Androidda) — Android komponentlari o'rtasida obyektlarni samarali seriyalash uchun maxsus interfeys.

Serializabledan foydalanish misoli:

import java.io.Serializable;

public class User implements Serializable {
    private String name;
    private int age;

    // Konstruktorlar, getterlar, setterlar
}

Androidda ko'pincha Parcelable ishlatiladi:

import android.os.Parcel;
import android.os.Parcelable;

public class User implements Parcelable {
    private String name;
    private int age;

    protected User(Parcel in) {
        name = in.readString();
        age = in.readInt();
    }

    public static final Creator<User> CREATOR = new Creator<User>() {
        @Override
        public User createFromParcel(Parcel in) {
            return new User(in);
        }

        @Override
        public User[] newArray(int size) {
            return new User[size];
        }
    };

    @Override
    public int describeContents() {
        return 0;
    }

    @Override
    public void writeToParcel(Parcel dest, int flags) {
        dest.writeString(name);
        dest.writeInt(age);
    }
}
