list与string数组之间的相互转化

java基础教程之list与string[]转化

 

List转换成String数组

 

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);   
        }
