Need help with fixing the code. Not able to run and getting a proper output.

Question : Write a computer program simulating RR scheduling for the 5 processes with arrival and service times as shown in the table. Your program will show the progress of each process and calculate start time, end time, initial wait time, total wait time of each process. Quantum =10, context switch =0.

Programming Language is Java.

id	Service time	arrival time
1	75	0
2	40	10
3	25	10
4	20	80
5	45	85

Need help to fix this Code:
