List
和 数组 互相转换

List<String> list = new ArrayList<String>();

list.add("java1");

list.add("java2");

String[] strs = list.toArray(new String[list.size()]);

for(String s : strs ) {

System.out.println(s);

}

 或

String str[] = list.toArray(new String[]{});

String数组转换成List

String[] bears = {"A", "B", "C", "D"};

List<String> bearList = Arrays.asList(bears );

for (String bear: bearList ) {

System.out.println(bear);

}
