java例程练习（List常用算法）

import java.util.*;

public class TestCollection {
public static void main(String[] args) {
List l1 = new LinkedList();
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 list1 = new LinkedList();
List list2 = new LinkedList();
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"));



}
