冒泡排序，从下到大排序

public class First {
public static void main(String[] args) {
System.out.println(“Hello World!”);
First f=new First();
int[] a=new int[]{4,7,2,3,8};
f.toSort(a);
}
public void toSort(int[] numbers){
String number=null;
for(int i=0;i<numbers.length-1;i++)
{
for(int j=0;j<numbers.length-1-i;j++)
{
if(numbers[j]>numbers[j+1])
{
int temp=numbers[j];
numbers[j]=numbers[j+1];
numbers[j+1]=temp;
}
}
}
System.out.println(“从小到大排序后的结果是:”);
for(int i=0;i<numbers.length;i++){
System.out.print(numbers[i]+" ");
}
}
}
