1. Aşağıdakı kodun nəticəsi nə olacaq?

package quiz;

public class JavaAzerbaijanException {
    public static void main(String[] args) {
        try {
            method();
        } catch (Exception e) {
            System.out.println("Caught in main");
        }
    }

    public static void method() throws Exception {
        try {
            throw new Exception("Thrown from method");
        } finally {
            System.out.println("Finally in method");
        }
    }
}

Caught in main

Finally in method və Caught in main

Thrown from method və Caught in main

Doğru

Yanlış

2. Aşağıdakı kodun nəticəsi nə olacaq?

package quiz;

public class JavaAzerbaijanException {
    public static void main(String[] args) {
        try {
            int result = calculate();
            System.out.println("Result: " + result);
        } catch (Exception e) {
            System.out.println("Caught Exception");
        }
    }

    public static int calculate() {
        try {
            throw new ArithmeticException();
        } finally {
            return 42;
        }
    }
}

Caught Exception

Caught Exception və Result: 42

3. Aşağıdakı kodun nəticəsi nə olacaq?

package quiz;

public class JavaAzerbaijanException {
    public static void main(String[] args) {
        try {
            int result = getValue();
            System.out.println("Result: " + result);
        } catch (Exception e) {
            System.out.println("Caught Exception");
        }
    }

    public static int getValue() {
        try {
            int number = 20;
            System.out.println(number / 0);
            return 10;
        } finally {
            return 20;
        }
    }
}

java.lang.ArithmeticException: / by zero at main

Result: 10

Result: 20

Caught Exception

4. Aşağıdakı kodun nəticəsi nə olacaq?

package quiz;

public class JavaAzerbaijanException {
    public static void main(String[] args) {
        try {
            Object x = new Integer(0);
            System.out.println((String) x);
        } catch (ClassCastException e) {
            System.out.println("Class cast exception caught");
        } finally {
            System.out.println("Finally block executed");
        }
    }
}

Class cast exception caught

Finally block executed

Class cast exception caught və Finally block executed

java.lang.Integer cannot be converted to java.lang.Object

Doğru

Yanlış

5. Aşağıdakı kodun nəticəsi nə olacaq?

package quiz;

public class JavaAzerbaijanException {
    public static void main(String[] args) {
        try {
            throw new NullPointerException("Test Exception");
        } catch (Exception e) {
            System.out.println("Caught Exception");
            System.exit(0);
        } finally {
            System.out.println("Finally block executed");
        }
    }
