Write a JAVA program of a player class || JAVA program on cricket
Problem Statements:
1. Define a class player having a player name, player_id, team, player type, Run rate,no-of-centuries,no-of-wickets, and method print_info().
2. Define two constructors for creating objects like Batsman, Bowler having fields like innings_played, run rate, wickets taken, score, etc.
3. Create methods update_stats(), Comp_stats(Player ob1,Player ob2)-to compare 2 player & return higher one(performance is determined on the basis of score made (in-case of batsman), wickets taken (in-case of bowler)).
4. Add method overloading for update_stats() method and print_info() method. Use objects as parameters to the methods.
5. Use static for generating player-id, final for the team name, and this for constructor chaining.
6.Use array of objects to store players, and print the top scorer batsman and highest wicket-taker among all.
