What is the output for the below code?
public class A{
int add(int i, int j){
return i+j;
}
}
public class B extends A{
public static void main(String argv[]){
short s = 9;
System.out.println(add(s,6));
}
}
public class A{
int add(int i, int j){
return i+j;
}
}
public class B extends A{
public static void main(String argv[]){
short s = 9;
System.out.println(add(s,6));
}
}A. Compile fail due to error on line no 2
B. Compile fail due to error on line no 9
C. Compile fail due to error on line no 8
D. 15
E. None of these
Answer: Option B
Solution(By Examveda Team)
Cannot make a static reference to the non-static method add(int, int) from the type A. The short s is autoboxed correctly, but the add() method cannot be invoked from a static method because add() method is not static.
