练习算法题的时候遇到这个错误：

Condition 'n<5' is always 'true'" less.. (Ctrl+F1)  
Inspection info: This inspection analyzes method control and data flow to report possible conditions that are always true or false, expressions whose value is statically proven to be  
constant, and situations that can lead to nllability contract violations.  
Variables, method parameters and return values marked as @Iullable or QIotIUu11 are treated as nullable (or not-null, respectively) and used during the analysis to check nllability  
contracts, e.g. report Iu1lPo intexExcept ion (NPE) errors that might be produced.  
More complex contracts can be defined using @Contract annotation, for example:  
@Contract(”\_ null -> nul1") 一method returns null if its second argument is null  
@Contract("\_ null -> null; 一!nul1 -> !nu11") 一method returns null if its second argument is null and not-null otherwise  
Contract(" true -> fai1') 一a typical asseItF alse method which throws an exception if true is passed to it  
The inspection can be configured to use custom @Iul1able  
@TotIu1l annotations (by default the ones from annotationsjar will be used)  
Condition 'n<5 && result== "continue"' is always 'false' ess.. (Ctrl+F1)

Variables, method parameters and return values marked as @Iullable or @lotIull are treated as nllable (or not-null, respectively) and used during the analysis to check nllbilily

More complex contracts can be defined using @C ontract annotation, for example:  
@Contract(”\_ null -> nu11") 一method returns null if its second argument is null  
Contract("\_ null -> mu1l; \_ !null -> !nu11') 一method returns null if its second argument is null and not-null otherwise

翻译后的意思：

检查信息：此检查分析方法控制和数据流，以报告可能始终为真或为假的表达式，其值被静态证明为  
常量以及可能导致违反不可告人性合同的情况。  
标记为@Iullable或QIotIUu11的变量，方法参数和返回值被视为可为空（或分别为非空），并在分析期间用于检查可填充性  
合约，例如报告可能会产生的IuIlPo intexExcept（NPE）错误。  
可以使用@Contract注释定义更复杂的合同，例如：  
@Contract（“ \_ null-> nul1”）如果第二个参数为null，则该方法返回null  
@Contract（“ \_ null-> null;一！nul1->！nu11”）如果一个方法的第二个参数为null，则该方法返回null，否则为非null  
Contract（“ true-> fai1'）一个典型的asseItF alse方法，如果将true传递给它，则会引发异常  
可以将检查配置为使用自定义@ Iul1able  
@ TotIu1l注释（默认情况下，将使用notificationsjar中的注释）  
条件'n <5 && result ==“ continue”'始终为'false'。.（Ctrl + F1）

主要原因：

循环语句的循环条件出现了问题-始终为真或假，修改一下就好了
