数组引用--冒泡排序 数组倒置为例

//倒置
public class Arriy {
    public static void main(String args[]){
        int data[]=new int[]{10,78,24,33,87,5,44,9,55};
        arrayinc(data);
        printarray(data);
        }
     public static void arrayinc(int array[]){
         int head=0;
         int tail=array.length-1;
         int center=array.length/2;
         for(int x=0;x<center;x++){
             int temp=array[head];
             array[head]=array[tail];
             array[tail]=temp;
             head++;
             tail--;
         }
        }
     public static void printarray(int arr[]){
         for(int x=0;x<arr.length;x++){
             System.out.print(arr[x]+"、");
         }
     }
}
