用java代码实现银行家算法

好的，以下是用 Java 实现银行家算法的代码：

import java.util.Scanner;

public class BankerAlgorithm {
    // 银行家算法实现
    public static void bankerAlgorithm(int[] available, int[][] max, int[][] allocation, int[][] need) {
        int n = available.length;
        int[] work = available.clone();
        boolean[] finish = new boolean[n];
        int[] sequence = new int[n];
        int count = 0;
        while (count < n) {
            boolean flag = false;
            for (int i = 0; i < n; i++) {
                if (!finish[i] && compareArray(need[i], work) <= 0) {
                    addArray(work, allocation[i]);
                    finish[i] = true;
                    sequence[count++] = i;
                    flag = true;
                }
            }
            if (!flag) {
                System.out.println("不满足安全性条件，无法完成所有进程的请求。");
                return;
            }
        }
        System.out.println("存在安全序列：");
        for (int i : sequence) {
            System.out.print("P" + i + " ");
        }
        System.out.println();
    }

    // 比较两个数组的大小（用于银行家算法中的判断）
    public static int compareArray(int[] a, int[] b) {
        int n = a.length;
        for (int i = 0; i < n; i++) {
            if (a[i] > b[i]) {
                return 1;
            } else if (a[i] < b[i]) {
                return -1;
            }
        }
        return 0;
    }

    // 数组加法
    public static void addArray(int[] a, int[] b) {
        int n = a.length;
        for (int i = 0; i < n; i++) {
            a[i] += b[i];
        }
    }

    // 主函数
    public static void main(String[] args) {
        Scanner in = new Scanner(System.in);

        System.out.print("请输入进程数：");
        int n = in.nextInt();

        System.out.print("请输入资源数：");
        int m = in.nextInt();

        int[] available = new int[m];
        int[][] max = new int[n][m];
        int[][] allocation = new int[n][m];
        int[][] need = new int[n][m];

        System.out.println("请输入 exist 数组：");
        for (int i = 0; i < m; i++) {
            available[i] = in.nextInt();
        }

        System.out.println("请输入 max 矩阵：");
        for (int i = 0; i < n; i++) {
            for (int j = 0; j < m; j++) {
                max[i][j] = in.nextInt();
            }
        }

        System.out.println("请输入 allocation 矩阵：");
        for (int i = 0; i < n; i++) {
            for (int j = 0; j < m; j++) {
                allocation[i][j] = in.nextInt();
            }
        }

        // 计算 need 矩阵
        for (int i = 0; i < n; i++) {
            for (int j = 0; j < m; j++) {
                need[i][j] = max[i][j] - allocation[i][j];
            }
        }

        bankerAlgorithm(available, max, allocation, need);
    }
}

请问还有其他问题需要回答吗？
