如何在Java中将Arrays值定为循环格式? [英] how to order Arrays value as circular format in java?

问题描述

我的数组值就像

String []值= {"1"，"2"，"3"，"4"，"5"，"6"，"7"，"8"，"9"，"10};

假设我将值"5"传递给tat数组，则应按

suppose if i pass value "5" to tat array, it should be ordered as like

{"5","6","7","8","9","10",1","2","3","4"};...

该怎么办?请有人帮忙吗?谢谢你

how to do?plz anyone help? thank u

推荐答案

您需要的是旋转.您可以使用 Collections.rotate()方法.将数组转换为列表并将其传递给方法.由于列表由数组支持，因此将旋转数组到位:

What you need is called rotation. You can use Collections.rotate() method. Convert the array to a list and pass it to the method. This will rotate the array in place since the list is backed by the array:

String[] value = {"1","2","3", "4","5","6","7","8","9","10"};
Collections.rotate(Arrays.asList(value), 5);

上面的代码会将数组旋转5距离.得到的 value 数组:

The above code will rotate the array by a distance of 5. The resulting value array:

[6, 7, 8, 9, 10, 1, 2, 3, 4, 5]
