输入3个数a,b,c，按大小顺序输出。

public class Ex34 {
    public static void main(String[] args)
    {
        int []arrays = {800,56,500};
        for(int i=arrays.length;--i>=0;)
        {
            for(int j=0;j<i;j++)
            {
                if(arrays[j]>arrays[j+1])
                {
                    int temp=arrays[j];
                    arrays[j]=arrays[j+1];
                    arrays[j+1]=temp;
                }
            }
        }
        for(int n=0;n<arrays.length;n++)
        System.out.println(arrays[n]);
