用0-9的阿拉伯数字，组成一组5位长的密码n1n2n3n4n5,要求n1=n5,n1<n2<n3>n4>n5,请用编程实现 比如说：0< 1 < 2 > 1>0

        int[] n=new int[5];//存放5位密码，从左到右
    	Random r=new Random();
    	n[0]=r.nextInt(8);//0-7
    	n[1]=r.nextInt(9);//0-8
    	n[1]=n[1]>n[0]?n[1]:n[0]+1;
    	n[2]=r.nextInt(10);//0-9
    	n[2]=n[2]>n[1]?n[2]:n[1]+1;
    	n[3]=r.nextInt(9);//0-8
    	n[3]=n[3]<n[2]?n[3]:n[2]-1;
    	n[3]=n[3]>n[0]?n[3]:n[0]+1;
    	n[4]=n[0];
    	System.out.println(Arrays.toString(n));

运行10次结果如下： [5, 6, 7, 6, 5] [2, 8, 9, 3, 2] [5, 6, 7, 6, 5] [0, 8, 9, 6, 0] [5, 6, 9, 6, 5] [2, 3, 4, 3, 2] [6, 7, 8, 7, 6] [7, 8, 9, 8, 7] [6, 7, 8, 7, 6] [6, 8, 9, 7, 6]
