本文整理了Java中org.apache.commons.lang3.Validate.isInstanceOf()方法的一些代码示例，展示了Validate.isInstanceOf()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.isInstanceOf()方法的具体详情如下：
包路径：org.apache.commons.lang3.Validate
类名称：Validate
方法名：isInstanceOf

Validate.isInstanceOf介绍

[英]Validates that the argument is an instance of the specified class, if not throws an exception.

This method is useful when validating according to an arbitrary class

Validate.isInstanceOf(OkClass.class, object);

The message of the exception is "Expected type: {type}, actual: {obj_type}"
[中]验证参数是否为指定类的实例，如果不是，则引发异常。
当根据任意类进行验证时，此方法非常有用

Validate.isInstanceOf(OkClass.class, object);

异常的消息是“预期类型：{type}，实际类型：{obj_type}”
