List转换成String数组

java代码
1. List<String> list = new ArrayList<String>();  
2. list.add("a1");  
3. list.add("a2");  
4. String[] toBeStored = list.toArray(new String[list.size()]);  
5. for(String s : toBeStored) {  
6.       System.out.println(s);  
7. }  
[java]
1. <span style="color:#134f5c;">List<String> list = new ArrayList<String>();
list.add("a1"); list.add("a2");
String[] toBeStored = list.toArray(new String[list.size()]);
for(String s : toBeStored)
{    
System.out.println(s);
}</span>
