Java Linked List 基本用法

建构

LinkedList L = new LinkedList();LinkedList<E> L = new LinkedList();

Example1 一般常用

 LinkedList<String> L = new LinkedList(); L.add("d"); //新增元素 L.add("c"); L.add("a"); L.add("b"); L.remove(0);  //remove()  删除第0个元素 会递补  Collections.sort(L); //排列String or Integer for(String s:L) {     System.out.println(s); } System.out.println(L.get(1));  //get() 取资料

Example2 元件的sort

import java.util.*;public class test {class NameCompare implements Comparator<A>{public int compare(A a1,A A2){return a1.GetName().compareTo(A2.GetName()); }}public static void main(String[] args) {new test().Go();}void Go(){LinkedList<A> LA = new LinkedList();A Tony = new A("Tony");A John = new A("John");A Andy = new A("Andy");LA.add(Tony);LA.add(John);LA.add(Andy);NameCompare NC = new NameCompare();Collections.sort(LA, NC); for(A An:LA) { System.out.println(An.Name); }}}class A{String Name;A(String Name){this.Name = Name;}public String GetName(){return Name;}}
