7. Java Program to implement Single Inheritance with method overriding.

 /* 7. 2019Syllabus Consider class person with fields name, address and date of birth and methods read_data() and show() and another class employee inherited form person class with fields emp_id, date of join and salary and methods read() and show(). Write java program to implement the concept of single inheritance with method overriding concepts for the above classes.*/
