Given:
class Mid {
public int findMid(int n1, int n2) {
return (n1 + n2) / 2;
}
}
public class Calc extends Mid {
public static void main(String[] args) {
int n1 = 22, n2 = 2;
// insert code here
System.out.print(n3);
}
}
Which two code fragments, when inserted at // insert code here, enable the code to compile and print 12?
- Calc c = new Calc();
int n3 = c.findMid(n1, n2); - int n3 = super.findMid(n1, n3);
- Calc c = new Mid();
int n3 = c.findMid(n1, n2); - Mid m1 = new Calc();
int n3 = m1.findMid(n1, n2); - int n3 = Calc.findMid(n1, n2);
Answer(s): A,D
Explanation:
Incorrect:
Not B: circular definition of n3.
Not C: Compilation error. line Calc c = new Mid(); required: Calc
found: Mid
Not E: Compilation error. line int n3 = Calc.findMid(n1, n2); non-static method findMid(int, int) cannot be referenced from a static context
