Given:
interface DoStuff2 {
float getRange(int low, int high);
}
interface DoMore {
float getAvg(int a, int b, int c);
}
abstract class DoAbstract implements DoStuff2, DoMore {
}
06. class DoStuff implements DoStuff2 {
07. public float getRange(int x, int y) {
08. return 3.14f;
09. }
10. }
11.
12. interface DoAll extends DoMore {
13. float getAvg(int a, int b, int c, int d);
14. }
What is the result?
