java中list和数组的相互转换

1 list转数组

// list转数组
List<String> strList = new ArrayList<String>();
strList.add("aaa");
strList.add("bbb");
strList.add("ccc");
String[] strArray = strList.toArray(new String[strList.size()]);  
System.out.println(Arrays.toString(strArray));

2 数组转list（Arrays.asList和Collections.addAll两种方法）

// 数组转list
List<String> strList = Arrays.asList("111","222","333");
System.out.println(strList);
 
String[] strArray = {"111","222","333"};
List<String> sList = new ArrayList<String>();
Collections.addAll(sList, strArray);
