Consider the following code. How many times will the body of the for loop execute when the main method is run?

class Parent {
    public void runLoop() {
        for (int i = 1; i <= 3; i++) {
            System.out.print(i + " ");
        }
    }
}

class Child extends Parent {
    @Override
    public void runLoop() {
        for (int i = 0; i < 4; i++) {
            System.out.print(i + " ");
        }
    }
}

public class Main {
    public static void main(String[] args) {
        Parent p = new Child();
        p.runLoop();
    }
