如何实现对从键盘输入的一组数据进行排序？

[空中乘客]

public class BubbleSort
{
public static void bubbleSort(int[] a)
{
int in,out;//内循环，外循环
for(out=a.length-1;out>0;out--)
for(in=0;in<out;in++)
{
if(a[in]>a[in+1])
swap(a,in,in+1);
}
for(int i=0;i<a.length;i++)
{
System.out.println(a[i]);
}
}
public static void swap(int[] a,int i,int j)
{
int temp=a[i];
a[i]=a[i+1];
a[i+1]=temp;
}
public static void main(String[] args)
{
int[] data={11,3,82,38,5,333,22,11};
bubbleSort(data);
}
}
请问我想从键盘动态输入一组数据进行排序应该怎么弄呢？

String aa[]=new String[3];
int i=0;
try{
BufferedReader reader = new BufferedReader(new InputStreamReader(System.in));
while(true){
if(reader.readLine().equals("exit")||i==3){
break;
}
aa[i]=reader.readLine();
i++;
}
}catch(Exception e){
e.printStackTrace();
}

排序使用Array.sort[Quote=引用 2 楼 barryhappy 的回复:]

Java code


import java.util.Arrays;
import java.util.Scanner;

public class F {

public static void main(String[] agrs) {
/*接收数据*/
System.out.println("数组的大小？");
Scanner ……
