Java-list and Arrays convert each other

List to array:

List List = new ArrayList (), List.add ("1"), List.add ("2"), final int size = List.size (); String[] arr = (string[]) List.toarray (new string[size]);

Array to list:

1. A more stupid method

string[] words = {...}; list<string> list = new arraylist<string> (words.length); for (String s:words) {List.add (s);}

2. Methods that you can also

Import java.util.Collections; List myList = new ArrayList (); string[] myStringArray = new string[] {"Java", "is", "Cool"}; Collections.addall (MyList, myStringArray);

3. This is OK.

List stooges = Arrays.aslist ("Larry", "Moe", "Curly");//list returned cannot execute add remove. You can use list List = new ArrayList (arrays.aslist (array));

string[] arr = new string[] {"1", "2"}; List List = Arrays.aslist (arr);
