java基礎教程之list與string[]轉化

List轉換成String陣列

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陣列

        String[] bears = {"A", "B", "C", "D"};   
        List<String> bearList = Arrays.asList(bears );   
        for (String bear: bearList ) {   
            System.out.println(bear);   
        }
