java - 添加用户输入升序的代码

Question

import java.util.Scanner;
import java.util.Arrays;
public class searchSorting 
{
    public static void main (String[]args)
    {
        String line;
        Scanner in = new Scanner(System.in);

        System.out.print("How many numbers you want to input?: ");
        line = in.nextLine();
        System.out.print("Input Number 1: " );
        line = in.nextLine();
        System.out.print("Input Number 2: ");
        line = in.nextLine();
        System.out.print("Input Number 3: " );
        line = in.nextLine();
        System.out.print("Input Number 4: ");
        line = in.nextLine();
        System.out.print("Input Number 5: " );
        line = in.nextLine();
    }
    public static void sortAscending (double[]arr)
    {
        Arrays.sort(arr); 
        System.out.printf("Sorted arr[] = %s", 
        Arrays.toString(arr)); 

}}

我对用于将用户输入的内容按升序排列的代码感到困惑。我已经按升序查找并尝试了多种资源，但似乎没有任何效果。我试过:

System.out.print("Input number 1: "+(i+1+":");

尝试添加输入而不是写出所有输入，但 i 是一个未知变量。

您应该使用数组来存储输入并使用循环来读取输入。

System.out.print("How many numbers you want to input?: ");
int num = in.nextInt();
double[] arr = new double[num];
for(int i = 0; i < num; i++){
   arr[i] = in.nextDouble();
}
sortAscending(arr);
