java例程练习（List常用算法）

import java.util.*; public class TestCollection { public static void main(String[] args) { List<String> l1 = new LinkedList<String>(); for(int i = 0; i <= 5; i++) { l1.add("a" + i); } System.out.println(l1); l1.add(3, "a100"); System.out.println(l1); l1.set(6, "a200"); System.out.println(l1); System.out.print((String)l1.get(2) + " "); System.out.println(l1.indexOf("a3")); l1.remove(1); System.out.println(l1); List<String> list1 = new LinkedList<String>(); List<String> list2 = new LinkedList<String>(); for(int i = 0; i <= 9; i++) { list1.add("a" + i); } System.out.println(list1); Collections.shuffle(list1); System.out.println(list1); Collections.reverse(list1); System.out.println(list1); Collections.sort(list1); System.out.println(list1); System.out.println(Collections.binarySearch(list1,"a5")); } }
