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. }  

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); }
