how to declare list in java code example
Example 1: how to create a list in java
import java.util.ArrayList;
import java.util.LinkedList;
import java.util.List;
class scratch{
public static void main(String[] args) {
List<Integer> aList = new ArrayList<>();
List<Integer> lList = new LinkedList<>();
}
}
Example 2: how to make java list
//Creating arraylist example
ArrayList<String> list = new ArrayList<String>();
//Adding objects in arraylist
list.add("Mango");
list.add("Banana");
//Change the element (index,"new value")
list.set(1,"Dates");
//Return the 2nd element, because index starts from 0
System.out.println("Returning element: " + list.get(1));
Example 3: declaration of list in java
ArrayList<String> list=new ArrayList<String>();//Creating arraylist
list.add("Mango");//Adding object in arraylist
list.add("Apple");
list.add("Banana");
list.add("Grapes");
//Printing the arraylist object
System.out.println(list);
Example 4: java make arraylist
//Create the Arraylist variable: . Replace the T with the type of
//data to be stored in the list.
ArrayList<T> exampleList = new ArrayList<>();
//You can now perform operations on this ArrayList
