EM-Tirupati Codeathon Series #08

[Question]
ROBOTIC CRICKET MATCH
you should write a program that simulate an automatic cricket match between India and Sri Lanka. The focus is the usage of Java Thread Constructs. Each Innings happens within its thread. You decide the 11 members of each team and provide two lists to the program. The first team is represented as team 1 and second team as team 2. You have to generate a random number for toss and if the number is between 0 and 1, team 1 bats first- else, if the number is between 1 and 2, then team 2 bats first. The batting happens by starting a thread. Each ball bowled is via a random number generator (that generates number rounded off, between 0 and 7). If the number is 0, batsman is out. If the number is 1, run is 1, number is 2, run is 2, number is 3, run is 3, number is 4, run is 4, number is 5, run is 5, number is 6, run is 6. If the number is exactly 7, then it is an extra 1 run and if it is 0, batsman is out). You have to do this until 10 batsmen get out in 1 team. The final score sheet will show as follows. Then you have to start another thread and do the same as above. The match ends either when the second team batsmen are out, with scores lesser than team 1 (team 1 wins), scores are tied (match is tied) and as soon score is greater than team 1 (team 2 wins). Each over is for 6 balls, if extra happens (number 7), 1 run is awarded and 1 extra ball is bowled. Extra run and Extra Ball is not part of batsman's account. Total Overs are 10. (T101 Match)
 
(No Need to Take Care of Changing Batsman Strike If Score is 1, 3 or 5. No Need to Record Bowling Figures of the Bowler in the Solution. No Need to Take Care Separately of Wide, No Balls, Byes, Leg Byes. There are No Free-Hits!).

[Explanation of Solution]
This Java program creates a virtual cricket match between India and Sri Lanka, with a focus on using multi-threading. It randomly selects which team bats first and then simulates their innings using separate threads. Each ball bowled is determined by a random number, with 0 indicating the batsman is out and 1 to 6 representing the runs scored. Extras (7) are also taken into account. The match includes two innings, and the program maintains a detailed scorecard for both teams, tracking player names, runs, and extras.
 
To ensure data integrity, the program employs multi-threading principles and uses locks when shared data is modified. After both innings are completed, the program calculates the total score for each team and determines the match result based on these scores. The final output displays comprehensive scorecards and declares the match result.
