Java8中字符串處置庫strman-java的應用示例。本站提示廣大學習愛好者：（Java8中字符串處置庫strman-java的應用示例）文章只能為提供參考，不一定能成為您想要的結果。以下是Java8中字符串處置庫strman-java的應用示例正文
引見
Strmen-java是一個字符串處置對象，你可以經由過程maven將它引入到項目中。Strmen-java為我們供給了一個異常完全且壯大的處理計劃，應用它可以處理簡直一切字符串處置場景。
應用
為了能在你的Java運用法式中應用strman-java，可以把這個包下載上去添加到你項目標lib目次中，假如應用的是Maven做項目治理，則只須要在你的pom.xml中參加以下依附便可：
<dependency> <groupId>com.shekhargulati</groupId> <artifactId>strman</artifactId> <version>0.2.0</version> <type>jar</type> </dependency>
假如是Gradle用戶則在build.gradle文件中添加以下代碼：
compile(group: 'com.shekhargulati', name: 'strman', version: '0.2.0', ext: 'jar'){
transitive=true
}
示例
上面就是Strman-java的應用示例：
import strman.Strman;
import java.util.Arrays;
import java.util.Optional;
