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!).

Points to Note

200 Marks will be Awarded to this Question. Pass Marks are at 120. You have to understand if you do not use any threading or async task execution in java, you will be awarded at the maximum 120- 140 marks, provided that your logic is working correctly. The Remaining 60-80 marks are given to showcase/prove your skills in Java Multi-Threading or Async Task Execution. You have to start the first thread for the first innings while the main program runs, then once the innings is complete, you have to make sure that the main program understands that. Similar way you have to start the second thread and note there might be shared objects or shared data to use. Please make sure you also understand/demonstrate thread safety.

[Explanation of Solution]

This Java program simulates a cricket match between India and Sri Lanka using multi-threading. It begins by randomly determining which team bats first and then runs the innings in separate threads.

Each ball bowled is generated with a random number from 0 to 7, where 0 means the batsman is out, 1 to 6 represent the runs scored, and 7 signifies an extra run. The match consists of two innings, and the program keeps track of batsmen, their scores, and extras.

The match result is determined based on the scores of both teams. If the second team's score is lower than the first team's, team 1 wins. If the scores are tied, it's a tie, and if the second team scores more, team 2 wins.

The program showcases multi-threading concepts to simulate the cricket match and provides a detailed scorecard at the end.
