Q:

arraylist to array java

Integer[] spam = new Integer[] { 1, 2, 3 };
List<Integer> list = Arrays.asList(spam);
9
List<Element> list = Arrays.asList(array);
4
String[] arr = list.toArray(new String[list.size()]);
4
List<String> list = new ArrayList<>();
list.add("a");
list.add("ab");
list.add("abc");
list.add("abcd");
// convert
String[] array = list.toArray();
5
/*
Get the Array to be converted.
Create the List by passing the Array as parameter in the constructor of the List with the help of Arrays. asList() method.
Return the formed List.
*/

String[] namedata = { "ram", "shyam", "balram" }; 

List<String> list = Arrays.asList(namedata);

ArrayList<String> ArrayLister=new ArrayList<>(){ArrayLister.add("Hi")};
String[] array=ArrayLister.toArray(String[]);
