说明

实现了FCFS和SJF两种调度算法，可以输入作业序列得到调度顺序和执行时间
使用姿势如下

import java.util.Scanner;

public class Test {
    static final String PROMPT = "**********\n1 for FCSC\n2 for SJF\n**********";
    public static void main(String args[]) {
        Scanner scanner = new Scanner(System.in);
        System.out.print("Input memory size (in MB): ");
        int size = scanner.nextInt();
        System.out.println("Input the schedule algorithm:\n" + PROMPT);
        int algorithm = scanner.nextInt();
        Schedule schedule = new Schedule(size, algorithm);
        schedule.work();
        schedule.printScheduleInfo();
    }
}
