尝试输出冒泡排序的数组

我正在尝试对数组进行冒泡排序,然后输出原始数据和已排序数据。它似乎工作,但当它输出数据时,它输出[l @ 486f03ec作为两个数组而不是数字。我不知道我做错了什么。我的代码是

import javax.swing.*;
import java.io.*;

public class Gates_sortingBubble{

public static void main(String[] args)throws IOException{

  JOptionPane.showMessageDialog (null, "Please enter five numbers.", "Sorting Arrays", JOptionPane.INFORMATION_MESSAGE);

  String number1s;
  number1s = JOptionPane.showInputDialog("Number 1: ");
  int number1 = Integer.parseInt(number1s);

  String number2s;
  number2s = JOptionPane.showInputDialog("Number 2: ");
  int number2 = Integer.parseInt(number2s);

  String number3s;
  number3s = JOptionPane.showInputDialog("Number 3: ");
  int number3 = Integer.parseInt(number3s);

  String number4s;
  number4s = JOptionPane.showInputDialog("Number 4: ");
  int number4 = Integer.parseInt(number4s);

  String number5s;
  number5s = JOptionPane.showInputDialog("Number 5: ");
  int number5 = Integer.parseInt(number5s);

  int[] numbers = {number1, number2, number3, number4, number5};

  sort(numbers);

 }

 public static void sort(int[] tosort){

  int[] original = tosort;

  int j;
  boolean flag = true;
  int temp;

  while(flag){       
     flag= false;  
     for( j=0;  j < tosort.length -1;  j++ ){
        if ( tosort[ j ] < tosort[j+1] ){   // change to > for ascending sort
           temp = tosort[ j ];              
           tosort[ j ] = tosort[ j+1 ];
           tosort[ j+1 ] = temp;
           flag = true;  
        }
     }
  } 

  print(tosort, original);
}   


public static void print(int[] sorted, int[] unsorted){

  JOptionPane.showMessageDialog (null, "Your original five numbers are: [" + unsorted + "]. \nYour new five numbers are: [" + sorted + "].", "Sorted Arrays", JOptionPane.INFORMATION_MESSAGE);

}


}

您可以在Arrays.toString(sorted)方法中使用print来获得所需的行为。

  

public static String toString(int [] a)

     

返回指定数组内容的字符串表示形式。字符串表示由数组元素的列表组成,用方括号括起来(“[]”)。相邻元素由字符“,”(逗号后跟空格)分隔。通过String.valueOf(int)将元素转换为字符串。如果a为null,则返回“null”。

     

参数:       a - 返回其字符串表示的数组

     

返回:       

的字符串表示形式

您需要在Arrays.toString中使用java.util
