Write a Java program A2p1.java with a public class A2p1 and no named packages to read from stdin information for several singers and dancers. You should design a superclass Person with appropriate constructor(s) to initialize member variables such as name (of type String), sex (of type String) and age (of type int). You should design two additional subclasses Singer and Dancer of the Person class with appropriate constructor(s) to initialize additional member variables such as favorite (of type String). You can add the toString method to these three classes to provide a suitable string representation for objects of these classes. Put all four classes in the same file. A sample run can look like the following (you can also try running it with standard input redirection): [~/temp] $ java A2p1 [kwang@computer] How many persons do you want to input? 3 Enter information for person 1: Name: Tom Sex ('F' or 'M') : M Age: 18 Singer or Dancer ('S' or 'D'): S Favorite song: songl Enter…
