[转]数组和ArrayList之间的相互转换

1、数组转 ArrayList

public static void main(String[] args) {
	String[] strArr = {"测试1","测试2","测试3"};
	List<String> strList = Arrays.asList(strArr);
	for (int i = 0; i < strList.size(); i++) {
		System.out.println(strList.get(i));
	}
}

2、ArrayList 转数组

public static void main(String[] args) {
	List<String> strList = new ArrayList<String>();
	strList.add("测试1");
	strList.add("测试2");
	strList.add("测试3");
	String[] strArr = (String[]) strList.toArray(new String[strList.size()]);
	for (int i = 0; i < strArr.length; i++) {
		System.out.println(strArr[i]);
	}
}
