Question ID: UK8296869
Given code of Test.java file:
package com.examtest.ocp;
 
class Parent {
    int var = 1000; // Line n1
 
    int getVar() {
        return var;
    }
}
 
class Child extends Parent {
    private int var = 2000; // Line n2
 
    int getVar() {
        return super.var; //Line n3
    }
}
 
public class Test {
    public static void main(String[] args) {
        Child obj = new Child(); // Line n4
        System.out.println(obj.var); // Line n5
    }
}
There is a compilation error in the code.

Question 2

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
How many of the above statements is/are correct?

Answer: C

public class Test {
    public static void main(String[] args) {
        Animal horse = new Horse();

                System.out.print(i * j + "\t");
            }
            System.out.println();
            if(i == 10) {
