使用java代码写一个进程调度算法

好的，我可以回答这个问题。进程调度算法是指操作系统如何为不同的进程分配 CPU 时间，以便最优化地利用 CPU 资源。以下是一个简单的Java代码示例，实现一个进程调度算法：

import java.util.*;

public class ProcessScheduler {

static Scanner scan = new Scanner(System.in);
static int n, quantum;
static String[] processName;
static int[] burstTime, waitingTime, turnaroundTime, remainingTime, arrivalTime;
static float avgWaitingTime, avgTurnaroundTime;

public static void main(String[] args) {

System.out.println("Enter the number of processes: ");
n = scan.nextInt();

processName = new String[n];
burstTime = new int[n];
waitingTime = new int[n];
turnaroundTime = new int[n];
remainingTime = new int[n];
arrivalTime = new int[n];

System.out.println("Enter the Process Name, Burst Time and Arrival Time for each process: ");

for (int i = 0; i < n; i++) {
System.out.println("\nProcess " + (i+1) + ": ");
System.out.println("Process Name: ");
processName[i] = scan.next();
System.out.println("Burst Time: ");
burstTime[i] = scan.nextInt();
System.out.println("Arrival Time: ");
arrivalTime[i] = scan.nextInt();

waitingTime[i] = 0;
turnaroundTime[i] = 0;
remainingTime[i] = burstTime[i];
}

System.out.println("\nEnter Time Quantum: ");
quantum = scan.nextInt();

// Applying Round Robin Algorithm
int t = 0, completed = 0;
boolean flag;
while (completed != n) {
flag = false;
for (int i = 0; i < n; i++) {
if (remainingTime[i] > 0) {
flag = true;
if (remainingTime[i] > quantum) {
t += quantum;
remainingTime[i] -= quantum;
} else {
t += remainingTime[i];
waitingTime[i] = t - burstTime[i] - arrivalTime[i];
remainingTime[i] = 0;
completed++;
}
}
}
if (!flag) {
break;
}
}

// Calculating Average Waiting Time and Turnaround Time
for (int i = 0; i < n; i++) {
turnaroundTime[i] = burstTime[i] + waitingTime[i];
avgWaitingTime += waitingTime[i];
avgTurnaroundTime += turnaroundTime[i];
}

avgWaitingTime /= n;
avgTurnaroundTime /= n;

System.out.println("\nProcess Scheduling Table:");
System.out.println("Process Name\tBurst Time\tArrival Time\tWaiting Time\tTurnaround Time");

for (int i = 0; i < n; i++) {
System.out.println(processName[i] + "\t\t" + burstTime[i] + "\t\t" + arrivalTime[i] + "\t\t" + waitingTime[i] + "\t\t" + turnaroundTime[i]);
}
System.out.println("\nAverage Waiting Time: " + avgWaitingTime);
System.out.println("Average Turnaround Time: " + avgTurnaroundTime);
}
}
