Create an ArrayList of Specific Size in Java

To create an ArrayList of specific size, you can pass the size as argument to ArrayList constructor while creating the new ArrayList.

Following the syntax to create an ArrayList with specific size.

</>
Copy
myList = new ArrayList<T>(N);

where N is the capacity with which ArrayList is created.

The size we mentioned is just the initial capacity with which the ArrayList is created. But, it does not limit you from adding elements beyond the size N, and expand the ArrayList.

Example 1 – Create an ArrayList with Specific Size

import java.util.ArrayList;

public class ArrayListExample {
	public static void main(String[] args) {
		ArrayList<String> names = new ArrayList<String>(3);
		names.add("Google");
		names.add("Apple");
	}
}
