Java List转换成String数组几种实现方式详解

Java List转换成String数组

实现代码：

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);
}

或

List<String> list = new ArrayList<String>();
list.add("a1");
list.add("a2");

String[] toBeStored = new String[al.size()];
list.toArray(toBeStored);
for (String s : toBeStored) {
 System.out.println(s);
}
