Java List轉換成String數組幾種實現方式詳解

Java List轉換成String數組

實現代碼：

 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); }
