Question
Assuming that all the necessary imports are done, what will be the output of the following Java program? class parent { int a; } class child extends parent { int b; void display() { super.a = b + 1; System.out.println(b + " " + i); } } class inheritance { public static void main(String args[]) { child obj = new child(); obj.a=1; obj.b=2; obj.display(); }}Options3 32 22 3Compilation Error
Solution
The output of the program will be a Compilation Error. This is because in the display() method of the child class, the variable 'i' is not defined or declared anywhere in the program. The correct code should be System.out.println(b + " " + a); instead of System.out.println(b + " " + i);.
