java 中关于选择排序的运行时错误

Question

我学会了选择排序，我尝试用java编码。但它有一个错误，我认为这是一个运行时错误。我不知道要在我的代码中修复什么。

这是代码：

import java.util.Scanner;

public class Main {

    public static void main(String args[])
    {

        int temp;

        Scanner sc=new Scanner(System.in);
        int number;
        int input=sc.nextInt();
        int [] carriage;
        carriage=new int[input];
        for(int i=0;i<input;i++)
        {
            number=sc.nextInt();
            carriage[i]=number;


        }
        int n=carriage.length;
        for(int i=0;i<n-1;i++)
        {
            for(int j=i+1;i<n;j++)
            {
                if(carriage[j]<carriage[i])
                {
                    temp=carriage[i];
                    carriage[i]=carriage[j];
                    carriage[j]=temp;
                }

            }
            System.out.println(carriage[i]+ " ");
        }
        sc.close();
    }
}

我想你想对用户提供的整数进行排序。您的代码有 2 个错误。以i开头的for循环中的一个，条件应该是i

public class Main {

    public static void main(String args[]) {

        int temp;

        Scanner sc = new Scanner(System.in);
        int number;
        System.out.println("Enter the number of integers to be sorted - ");
        int input = sc.nextInt();
        int[] carriage;
        carriage = new int[input];
        for (int i = 0; i < input; i++) {
            System.out.println("Enter the "+ i+1 +"number  - ");
            number = sc.nextInt();
            carriage[i] = number;
        }
        int n = carriage.length;
        for (int i = 0; i < n; i++) {
            for (int j = i + 1; j < n; j++) {
                if (carriage[j] < carriage[i]) {
                    temp = carriage[i];
                    carriage[i] = carriage[j];
                    carriage[j] = temp;
                }

            }
            System.out.println(carriage[i] + " ");
        }
        sc.close();
    }
}
