以此记录作为2016的结束吧，祝大家2017年收货更好的自己
int型数组转换为List<Integer>对象：
static List<Integer> intArrayToListInteger(int[] ints) {
List<Integer> intList = new ArrayList<>(ints.length);
for (int anInt : ints) {
intList.add(anInt);
}
return intList;
}
List<Integer>对象转换为int型数组:
static int[] listIntegerToIntArray(List<Integer> list) {
int[] ints = new int[list.size()];
for (int i = 0; i < list.size(); ++i) {
ints[i] = list.get(i);
}
return ints;
}
List<Integer>对象转换为List<String>对象：
static List<String> listIntegerToListString(List<Integer> integerList) {
List<String> stringList = new ArrayList<>(integerList.size());
for (Integer anInt : integerList) {
stringList.add(String.valueOf(anInt));
}
return stringList;
}
List<String>对象转换为List<Integer>对象：
static List<Integer> listStringToListInteger(List<String> stringList) {
List<Integer> intList = new ArrayList<>();
for (String s : stringList) {
intList.add(Integer.valueOf(s));
}
return intList;
}
String型数组转换为List<String>对象：
static List<String> stringArrayToListInteger(String[] strings) {
List<String> stringList = new ArrayList<>(Arrays.asList(strings));
return stringList;
}
List<String>对象转换为String型数组：
static String[] listStringToStringArray(List<String> stringList){
String[] strings = stringList.toArray(new String[0]);
return strings;
}
祝好
