Which two code fragments inserted at end of the program, will allow to compile? 1. class AllMath extends DoMath { double getArea(int r); } 2. interface AllMath implements MathPlus { double getVol(int x, int y); } 3. interface AllMath extends DoMath { float getAvg(int h, int l); } 4. class AllMath implements MathPlus { double getArea(int rad); } 5. abstract class AllMath implements DoMath, MathPlus { public double getArea(int rad) { return rad * rad * 3.14; } } interface DoMath { double getArea(int rad); } interface MathPlus { double getVol(int b, int h); } /* Missing Statements ? */
