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);
}
}

Here is the output for the code above:

Fruits: [Apple, Banana, Cherry]
Fruits after .clear(): []
