用Java语言写冒泡排序

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");  
         }  
      }  
  }
