Code Example 3: A ScriptEngineFactory object provides detailed information about the engine it provides.

ScriptEngineManager mgr = new ScriptEngineManager(); List<ScriptEngineFactory> factories = mgr.getEngineFactories(); for (ScriptEngineFactory factory: factories) { System.out.println("ScriptEngineFactory Info"); String engName = factory.getEngineName(); String engVersion = factory.getEngineVersion(); String langName = factory.getLanguageName(); String langVersion = factory.getLanguageVersion(); System.out.printf("\tScript Engine: %s (%s)\n", engName, engVersion); List<String> engNames = factory.getNames(); for(String name: engNames) { System.out.printf("\tEngine Alias: %s\n", name); } System.out.printf("\tLanguage: %s (%s)\n", langName, langVersion); }
