def map = [
	  1: [lang:"Groovy", isbn: 654, book: "Groovy Pro"],
	  2: [lang:"Java", isbn: 981, book: "Java Pro"],
	  3: [lang:"C++", isbn: 236, book: "C++ Pro"],
	  4: [lang:"Python", isbn: 708, book: "Python Pro"]]
 
def langs = map.collect{entry -> entry.value.lang}

println langs

println langs.get(0)  

  
  
/*
run:
  
[Groovy, Java, C++, Python]
Groovy
  
*/
