size of arraylist code example

Example 1: how to make arraylist of fixed size

List<Integer> arr = Arrays.asList(new Integer[10]);

Example 2: arraylist length java

aList.size()

Example 3: ArrayList size() method in java

import java.util.ArrayList;
public class ArrayListSizeMethodExample
{
   public static void main(String[] args)
   {
      ArrayList<Integer> al = new ArrayList<Integer>();
      int s = al.size();
      System.out.println("size of ArrayList: " + s);
      al.add(25);
      al.add(64);
      al.add(73);
      s = al.size();
      System.out.println("size of ArrayList after adding elements: " + s);
      al.clear();
      s = al.size();
      System.out.println("size of ArrayList after clearing elements: " + s);
   }
}

Example 4: arraylist length

list.size()

Example 5: java list length

ArrayList<String> listOfBanks = new ArrayList<>(); 
int size = listOfBanks.size(); 
System.out.println("size of array list after creating: " + size);

Example 6: ArrayList size() method in java

import java.util.ArrayList;
public class ArrayListSizeMethodExample
{
   public static void main(String[] args)
   {
      ArrayList<String> al = new ArrayList<String>();
      int s = al.size();
      System.out.println("size of ArrayList: " + s);
      al.add("red");
      al.add("blue");
      al.add("green");
      s = al.size();
      System.out.println("size of ArrayList after adding elements: " + s);
      al.clear();
      s = al.size();
      System.out.println("size of ArrayList after clearing elements: " + s);
   }
}
