ArrayList removeIf() Method in Java with Examples

// Java program to demonstrate the use of removeIf()
// method with ArrayList of Integers
import java.util.ArrayList;

public class GFG {
    public static void main(String[] args) {

        // create an ArrayList of integers
        ArrayList<Integer> num = new ArrayList<>();

        // Adding numbers to 
        // the ArrayList
        num.add(23);
        num.add(32);
        num.add(45);
        num.add(63);

        // Using removeIf() method to remove 
        // numbers divisible by 3
        num.removeIf(n -> (n % 3 == 0));

        System.out.println(num);
    }
}

// Java program to demonstrate the use of removeIf()
// method with ArrayList of Strings
