Hi, I am stuck in writing the Lambda expression for the code below, would be great if anyone can help, thanks

import java.util.List;

import java.util.ArrayList;

import java.util.stream.*;

class Toy

{

private double price;

private String color;

public Toy (String color, double price)

{

this.color = color;

this.price = price;

}

public double getPrice ()

{

return price;

}

public String getColor ()

{

return color;

}

}

class TestToy

{

public static void main (String [ ] args)

{

List toys = new ArrayList ();

toys.add (new Toy ("red", 10));

toys.add (new Toy ("yellow", 20));

toys.add (new Toy ("red", 10));

/* Insert the code fragment here */

System.out.printf ("Total Price of Red Toys: %.2f%n", totalPrice);

}

}

Write Lambda expression to find the total price of red toy price.
