Consider the following classes: public class Sum public int docalc) return 10 public int doAnothercalc) return 20; public class BigSum extends Sum ( public int docalc) f int x = super. doCalc(); return x + doAnotherCalc)i public int doAnothercalc) return 100 What is displayed to the console after the following code segment executes: sum s = new BigSum(); System.out.println(s.doCalc()) 30 ? 110 10 20 100
