Question 4

Question ID: UK8296889
Given code of Test.java file:
package com.examtest.ocp;
 
class GrandParent {}
 
class Parent extends GrandParent {}
 
class Child extends Parent {}
 
class GrandChild extends Child {}
 
public class Test {
    public static void main(String... args) {
        GrandParent obj = new Child();
        if(!(obj instanceof GrandChild gc)) {
            System.out.print("Not a GrandChild");
            /*INSERT-1*/
        } 
        /*INSERT-2*/
        System.out.println(gc); //Line n2
    }
}
And the statements:
1. Above code causes compilation error
2. Above code compiles successfully and prints: Not a GrandChild
3. To resolve compilation error, replace /*INSERT-1*/ with return;
4. To resolve compilation error, replace /*INSERT-2*/ with else

        } catch(ArithmeticException e) {
            throw (RuntimeException)e;
        }
    }
    
    public static void main(String[] args) {
        try {
            div(5, 0);
        } catch(ArithmeticException e) {
            System.out.println("AE");
        } catch(RuntimeException e) {
