java 数组

动态初始化

1，java数组声明

    private int array[];    private int[] score;

2，java数组分配内存空间，初始化

score=new int[3]; 

3，for循环赋值

for (int i=0;i<score.length;i++){            score[i]=i*3+1;        }

4，循环输出值

for (int i=0;i<score.length;i++){            Log.i("info",score[i]+"");        }

静态初始化
1，声明并赋值

private int array[]={1,2,3,4,5};

2，循环输出

 for (int i=0;i<array.length;i++){            Log.i("info",array[i]+"");        }

冒泡排序

 @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);       int score[]={65,45,23,88,4,400};        for(int i=0;i<score.length;i++){             for (int j=i+1;j<score.length;j++){                 if (score[i]<score[j]){                     int temp=score[i];                     score[i]=score[j];                     score[j]=temp;                 }             }            Log.i("info","第"+i+"次");            for (int j=0;j<score.length;j++){                Log.i("info", score[j] + "");            };        }        for (int i=0;i<score.length;i++){            Log.i("info", score[i] + "");        }    }
