Java数据结构和算法之冒泡排序(动力节点Java学院整理)

public class BubbleSort{
 public static void main(String[] args){
  int score[] = {67, 69, 75, 87, 89, 90, 99, 100};
  for (int i = 0; i < score.length -1; i++){ //最多做n-1趟排序
  for(int j = 0 ;j < score.length - i - 1; j++){ //对当前无序区间score[0......length-i-1]进行排序(j的范围很关键，这个范围是在逐步缩小的)
   if(score[j] < score[j + 1]){ //把小的值交换到后面
   int temp = score[j];
   score[j] = score[j + 1];
   score[j + 1] = temp;
   }
  }  
  System.out.print("第" + (i + 1) + "次排序结果：");
  for(int a = 0; a < score.length; a++){
   System.out.print(score[a] + "\t");
  }
  System.out.println("");
  }
  System.out.print("最终排序结果：");
  for(int a = 0; a < score.length; a++){
   System.out.print(score[a] + "\t");
  }
 }
 }
