The ScriptEngine interface is the fundamental interface whose methods must be fully functional in every implementation of this specification. These methods provide basic scripting functionality. Applications written to this simple interface are expected to work with minimal modifications in every implementation. It includes methods that execute scripts, and ones that set and get values. In short, to get the ScriptEngine by name you should:Create a new ScriptEngineManager. The ScriptEngineManager implements a discovery and instantiation mechanism for ScriptEngine classes and also maintains a collection of key\/value pairs storing state shared by all engines created by the Manager.Use the getEngineByName(String shortName) API method to look up and create a ScriptEngine for a given name.Then you can use the eval(String script) method to execute a script.Let\u2019s take a look at the code snippet that follows:\r\n\r\npackage com.javacodegeeks.snippets.core;\r\n\r\nimport javax.script.ScriptEngineManager;\r\nimport javax.script.ScriptEngine;\r\nimport javax.script.ScriptException;\r\n \r\npublic class GetScriptEngineByName {\r\n    public static void main(String[] args) {\r\n\r\n  ScriptEngineManager manager = new ScriptEngineManager();\r\n \r\n\r\n  \/\/ Create an instance of script engine using the engine name. In this example we use JavaScript\r\n\r\n  ScriptEngine engine = manager.getEngineByName(\"JavaScript\");\r\n \r\n\r\n  try {\r\n\r\n\r\nengine.eval(\"print('Hello JavaCodeGeeks Fellows');\");\r\n\r\n  } catch (ScriptException e) {\r\n\r\n\r\ne.printStackTrace();\r\n\r\n  }\r\n    }\r\n}\r\n\r\n\r\nOutput:\r\n\r\nHello JavaCodeGeeks Fellows\r\n\r\n \r\nThis was an example of how to get the ScriptEngine by name.","publisher":{"@id":"#Publisher","@type":"Organization","name":"Examples Java Code Geeks","logo":{"@type":"ImageObject","url":"\/wp-content\/uploads\/2013\/05\/JavaCodeGeeks-logo.png"},"sameAs":["https:\/\/feeds.feedburner.com\/examplesjavacodegeeks","https:\/\/www.facebook.com\/javacodegeeks","https:\/\/twitter.com\/javacodegeeks","https:\/\/www.linkedin.com\/groups\/3810709\/","https:\/\/www.youtube.com\/channel\/UCxoUc7Rar2q90Gu0nT2ffuQ","https:\/\/github.com\/javacodegeeks\/"]},"sourceOrganization":{"@id":"#Publisher"},"copyrightHolder":{"@id":"#Publisher"},"mainEntityOfPage":{"@type":"WebPage","@id":"https:\/\/examples.javacodegeeks.com\/java-development\/core-java\/script\/get-script-engine-by-name\/","breadcrumb":{"@id":"#Breadcrumb"}},"author":{"@type":"Person","name":"Ilias Tsagklis","url":"https:\/\/examples.javacodegeeks.com\/author\/ilias-tsagklis\/"},"image":{"@type":"ImageObject","url":"https:\/\/examples.javacodegeeks.com\/wp-content\/uploads\/2012\/12\/java-logo.jpg","width":1200,"height":150}}
