Question

Can you change the code below to remove the repeated lines of code and use a loop to draw 4 sides of the square?please show screenshots of your workimport java.util.*;import java.awt.*;public class TurtleDrawSquare{public static void main(String[] args){World world = new World(300,300);Turtle yertle = new Turtle(world);// Change the following code to use a for loop to draw the squareyertle.forward();yertle.turn(90);yertle.forward();yertle.turn(90);yertle.forward();yertle.turn(90);yertle.forward();yertle.turn(90);world.show(true);}}

Answer 1

The repeated lines of code for drawing a square can be replaced with a for loop that iterates four times, handling the forward movement and turn for each side of the square.

Step-by-step explanation:

The code provided for drawing a square with a Turtle in Java can be optimized by using a for loop. The repetitive actions of moving forward and turning can be executed inside a loop that runs four times, once for each side of the square. Here's how you can change the code:

for (int i = 0; i < 4; i++) {
yertle.forward(50); // assuming we want to move 50 pixels forward
yertle.turn(90); // a 90-degree turn for square corners
}

By using a for loop, we eliminate the repeated lines and make the code more concise and easier to maintain or change, such as if you want to modify the size of the square or draw a different polygon.
