用JAVA写以下代码：统计全班学生成绩。输入学生的学号及语文、数学、英语成绩，输出学生各科成绩信息、平均成绩和总成绩。（二维数组及循环）

以下是用JAVA实现统计全班学生成绩的代码，其中使用了二维数组和循环：

import java.util.Scanner;

public class Main {
    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);
        System.out.print("请输入班级人数：");
        int n = scanner.nextInt();
        String[][] students = new String[n][4];
        double[] scores = new double[n];
        double sum = 0;
        int maleCount = 0;
        int femaleCount = 0;
        for (int i = 0; i < n; i++) {
            System.out.print("请输入第" + (i + 1) + "个学生的姓名：");
            students[i][0] = scanner.next();
            System.out.print("请输入第" + (i + 1) + "个学生的性别（男/女）：");
            students[i][1] = scanner.next();
            System.out.print("请输入第" + (i + 1) + "个学生的语文成绩：");
            students[i][2] = scanner.next();
            System.out.print("请输入第" + (i + 1) + "个学生的数学成绩：");
            students[i][3] = scanner.next();
            scores[i] = Double.parseDouble(students[i][2]) + Double.parseDouble(students[i][3]);
            sum += scores[i];
            if (students[i][1].equals("男")) {
                maleCount++;
            } else {
                femaleCount++;
            }
        }
        double average = sum / n;
        System.out.println("学生各科成绩信息如下：");
        for (int i = 0; i < n; i++) {
            System.out.println(students[i][0] + "的语文成绩为：" + students[i][2] + "，数学成绩为：" + students[i][3]);
        }
        System.out.println("学生平均成绩为：" + average);
        System.out.println("学生总成绩为：" + sum);
        System.out.println("班级男女比例为：" + maleCount + ":" + femaleCount);
    }
}
