[代碼] 數組->List (StringArrayTest.java)
01 |
import java.util.Arrays; |
02 |
import java.util.List; |
03 |
import java.util.ArrayList; |
04 |
05 |
public class StringArrayTest |
06 |
{ |
07 |
public static void main(String[]
args) |
08 |
{ |
09 |
String[]
words = {"ace", "boom", "crew", "dog", "eon"}; |
10 |
|
11 |
List<String>
wordList = Arrays.asList(words); |
12 |
|
13 |
for (String
e : wordList) |
14 |
{ |
15 |
System.out.println(e); |
16 |
} |
17 |
} |
18 |
} |
[代碼] 比較傻的做法
1 |
String[]
words = { ... }; |
2 |
List<String>
list = new ArrayList<String>(words.length); |
3 |
for (String
s : words) { |
4 |
list.add(s); |
5 |
} |
[代碼] 這方法也還可以
1 |
import java.util.Collections; |
2 |
3 |
List
myList = new ArrayList(); |
4 |
String[]
myStringArray = new String[]
{"Java", "is", "Cool"}; |
5 |
6 |
Collections.addAll(myList,
myStringArray); |
