介绍

Strmen-java是一个字符串处理工具，你可以通过maven将它引入到项目中。Strmen-java为我们提供了一个非常完整且强大的解决方案，使用它可以解决几乎所有字符串处理场景。

使用

为了能在你的Java应用程序中使用strman-java，可以把这个包下载下来添加到你项目的lib目录中，如果使用的是Maven做项目管理，则只需要在你的pom.xml中加入如下依赖即可：

<dependency>
<groupId>com.shekhargulati</groupId>
<artifactId>strman</artifactId>
<version>0.2.0</version>
<type>jar</type>
</dependency>

如果是Gradle用户则在build.gradle文件中添加如下代码：

compile(group:'com.shekhargulati',name:'strman',version:'0.2.0',ext:'jar'){
transitive=true
}

示例

下面便是Strman-java的使用示例：

importjava.util.Arrays;
importjava.util.Optional;
