Java 数组实现冒泡排序算法

java 数组实现冒泡排序，小到大排序

//冒泡排序法，小到大排序

public class TestArray
{
public static void main(String  args[ ]){
int  i , j ;
int  a[ ] = { 5,9,6,8,7};
for  ( i = 0 ; i < a.length-1; i ++ ) {
int  k = i;
for  ( j = i ; j < a.length ;  j++ )
if  ( a[j]<a[k] )
k = j; //找到最小的元素
int  temp =a[i];
a[i] = a[k];
a[k] = temp;
}
for  ( i =0 ; i<a.length; i++ )
System.out.print(a[i]+"  ");
System.out.println( );
}
