在Java中生成任意两个随机字符 [英] Generating a random character out of any two in Java

问题描述

如何在两个特定字符之间生成随机字符？例如;我想生成'h'或'v'中的任何一个。

How do I generate a random character between two specific characters? For e.g; I want to generate either one of 'h' or 'v'.

谢谢

推荐答案

如果你想生成一个角色，你说，无论是h还是v，你都可以使用随机类，如此处所示。如果例如随机数大于0.5，则选择v，否则选择h。

If you want to generate a character, as you say, either h or v, you can generate a random number using the Random class as shown here. If for instance the random number is greater than 0.5, then choose v, if otherwise, choose h.

另一方面，如果你有一系列字母，你可以生成一个包含所需字符的数组，并生成一个随机数，用作选择随机字母的索引，否则，您可以生成65（Aschii for A）和90（Aschii for Z）之间的随机数。您可以在此处找到更多Aschii字符

On the other hand, if you have a range of letters, you can either generate an array with the characters you want and generate a random number which will be used as an index to choose the random letter, or else, you can generate random number between 65 (Aschii for A) and 90 (Aschii for Z). You can find more Aschii characters here
