Intermediate Java(7) - LinkedList Program

Continue..

import java.util.*;

public class apples{

public static void main(String[] args){

String[] things={"apple","orange","meat","bacon","mango"};

List<String> list1 = new LinkedList<String>();

for(String x:things)

list1.add(x);

String[] things2 = {"sausage","bacon","apples","pot"};

List<String> list2 = new LinkedList<String>();

for (String y:things2)

list2.add(y);

list1.addAll(list2);

list2 = null;

printMe(list1);

removeStuff(list1,2,5);

printMe(list1);

reverseMe(list1);

}

private static void printMe(List<String> l){

for (String b:l)

System.out.printf("%s ", b);

System.out.println();

}

private static void removeStuff(List<String> l, int from,int to){

l.subList(from, to).clear(); → 該list的Item(2)至(4)會清除

}

private static void reverseMe(List<String> l){

ListIterator<String> bobby =l.listIterator(l.size());

while(bobby.hasPrevious()) → 如果list1之前有內容

System.out.printf("%s ", bobby.previous()); → 打印出list1之前的內容(倒轉印)

}

}

這是運行時的結果:

apple orange meat bacon mango sausage bacon apples pot

apple orange sausage bacon apples pot

pot apples bacon sausage orange apple
