Java List转换成String数组几种实现方式详解

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); } 

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); }
