Java 类定义与排序：寻找中间数

import java.util.Scanner; import java.util.Arrays; public class Main { public static void main(String[] args) { Scanner scanner = new Scanner(System.in); double a = scanner.nextDouble(); double b = scanner.nextDouble(); double c = scanner.nextDouble(); double d = scanner.nextDouble(); double e = scanner.nextDouble();

    double[] arr = {a, b, c, d, e};
    double mid = findMiddleNumber(arr);
    
    System.out.printf(".2f", mid);
}

public static double findMiddleNumber(double[] arr) {
    Arrays.sort(arr);
    return arr[arr.length / 2];
}

}
