Qanday qilib siz chaqirishlar stekida yuqoriroq xatoliklarni chiqarasiz?

Men throw kalit so'zidan foydalanaman, bu orqali istisnoni qayta yuborish yoki yangi istisno yaratish.

public void method1() throws CustomException {
    try {
        // Biror kod, u AnotherException chiqarishi mumkin
        method2();
    } catch (AnotherException e) {
        // AnotherException ni tutamiz
        // Uni CustomException ga o'rab, yuqoriga yuboramiz
        throw new CustomException("Method2 da xato: " + e.getMessage(), e);
    }
}

public void method2() throws AnotherException {
    // Biror kod, istisno chiqarishi mumkin
    throw new AnotherException("Method2 da nimadir noto'g'ri bo'ldi");
}

class CustomException extends Exception {
    public CustomException(String message, Throwable cause) {
        super(message, cause);
    }
}

class AnotherException extends Exception {
    public AnotherException(String message) {
        super(message);
    }
}

Yoki, agar faqat ushlangan istisnoni yuqoriga yubormoqchi bo'lsangiz, yangi yaratmasdan:

public void methodA() throws SomeException {
    try {
        methodB();
    } catch (SomeException e) {
        // Log qilish yoki boshqa harakatlar
        // Shu istisnoni yuqoriga yuboramiz
        throw e;
    }
}

public void methodB() throws SomeException {
    // SomeException chiqarishi mumkin
    throw new SomeException("MethodB da xato");
}

class SomeException extends Exception {
    public SomeException(String message) {
        super(message);
    }
}
