Java的assert语句可以允许您指定一条消息吗? [英] Can java's assert statement allow you to specify a message?

问题描述

似乎喜欢在断言失败时让断言显示消息是很有用的.

Seems likes it might be useful to have the assert display a message when an assertion fails.

当前会抛出AssertionError，您能为其指定自定义消息吗?

Currently an AssertionError gets thrown, can you specify a custom message for it?

您能否展示一个用于执行此操作的示例机制(除了创建自己的异常类型并将其抛出之外)?

Can you show an example mechanism for doing this (other than creating your own exception type and throwing it)?

推荐答案

您当然可以:

assert x > 0 : "x must be greater than zero, but x = " + x;
