本文整理了Java中org.apache.commons.lang.Validate类的一些代码示例，展示了Validate类的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。Validate类的具体详情如下：
包路径：org.apache.commons.lang.Validate
类名称：Validate

Validate介绍

[英]This class assists in validating arguments.

The class is based along the lines of JUnit. If an argument value is deemed invalid, an IllegalArgumentException is thrown. For example:

Validate.isTrue( i > 0, "The value must be greater than zero: ", i); 
Validate.notNull( surname, "The surname must not be null");

[中]此类帮助验证参数。
这个类是基于JUnit的。如果参数值被视为无效，则抛出IllegalArgumentException。例如：

Validate.isTrue( i > 0, "The value must be greater than zero: ", i); 
Validate.notNull( surname, "The surname must not be null");
