Java List转换成String数组

实现代码：

List<String> list = new ArrayList<String>(); 
("a1"); 
("a2"); 
String[] toBeStored = (new String[()]); 
for(String s : toBeStored) { 
  (s); 
} 

或 

List<String> list = new ArrayList<String>(); 
("a1"); 
("a2"); 
   
String[] toBeStored = new String[()]; 
(toBeStored); 
for (String s : toBeStored) { 
  (s); 
}
