java 冒泡排序 单循环

今天陪同事面试，同事问到了单循环冒泡排序，考住了！自己回来试了一下，代码如下所示：

public static void main(String[] args) {
		int [] stars = {10,2,21,9,7,6,12,8,1,98,27,32,11,14,11};
		int temp = 0;
		int lengths = stars.length-1;
		for(int j=0 ; j<lengths ; j++){
	        if(stars[j] > stars[j + 1]){  
	            temp = stars[j];  
	            stars[j] = stars[j+1];  
	            stars[j+1] = temp;  
	        }
			if(j == lengths - 1){
				lengths = lengths - 1;
				j = -1;
			}
		}
		for(int a = 0 ; a < stars.length ; a++)  
	        System.out.print( stars[a] + ",");     
		}
	}
