LinkedList&Collections 클래스 활용 예제

추가적으로 Iterator 활용해보기

import java.util.Collections;
import java.util.Iterator;
import java.util.LinkedList;

public class LinkedListEx {
	static void printList(LinkedList<String> list) {
		Iterator<String> it = list.iterator();
		while(it.hasNext()) {
			System.out.print(it.next()+" ");
		}
		System.out.println("");
	}
	
	public static void main(String args[]) {
		LinkedList<String> myList = new LinkedList<String>();
		String[] names = {"Python", "Java", "Database", "Network"};
		for(String s : names) {
			myList.add(s);
		}
		printList(myList);
		
		System.out.println(myList);
		Collections.sort(myList);	//문자순 정렬
		System.out.println(myList);
		Collections.reverse(myList);	//역순
		System.out.println(myList);
	}
	
}
