Java .clear()

The .clear() method in Java removes all elements from an ArrayList. After invoking this method, the ArrayList gets empty, but its capacity remains unchanged. The method does not return a value.

Syntax

myArrayList.clear();

• myArrayList: The ArrayList to be cleared.

Example

The example below shows the use of the .clear() method:

import java.util.ArrayList;

public class Main {
  public static void main(String[] args) {
    // Creating an ArrayList
    ArrayList<String> fruits = new ArrayList<>();

    // Adding elements to the ArrayList
    fruits.add("Apple");
    fruits.add("Banana");
    fruits.add("Cherry");

    // Printing the ArrayList
    System.out.println("Fruits: " + fruits);

    // Clearing the ArrayList
    fruits.clear();

    // Printing the cleared ArrayList
    System.out.println("Fruits after .clear(): " + fruits);
  }
}
