代码实现:

　　

package com.datastruct.sort;

import java.util.Arrays;

public class InsertSort {
    
    public static void insertSort(int [] array)
    {
        for(int i = 1;i<array.length;i++)
        {
            int currentIndex = i-1;
            int currentValue = array[i];
            //开始循环移动
            while(currentIndex>=0&&currentValue<=array[currentIndex])
            {
                array[currentIndex+1] = array[currentIndex];
                currentIndex--;
            }
            
            array[currentIndex+1] = currentValue;
        }
    }
    
    public static void main(String[] args) {
        int [] arr = {101,34,228,-1,3};
        insertSort(arr);
        System.out.println(Arrays.toString(arr));
    }

}

 

 

运行的程序结果:

　　[-1, 3, 34, 101, 228]
