Triangle Program won't output the results

Question

Design a class named Triangle that extends GeometricObject It must contain:

Three double data fields named side1, side2, and side3 with default values 1.0 to denote three sides of the triangle

A no-arg constructor that creates a triangle with specified side1, side2,and side3.

The accessor methods for all three data fields.

A method named getArea() that returns the area if this triangle.

A method named getPerimeter() that returns the perimeter of this triangle.

*A method named toString() that returns a string description for the triangle.

For the formula to compute the area of a triangle, see ProgrammingExercise 2.15( in An introduction to java programming 9th edition) The toString() method is implemented as follows:

return " Triangle: side1 = " + side1 + " side2 = " + side2 + " side3 " + side3;

Write a test program that prompts the user to enter three sides of the triangle, a color, and a boolean value to indicate whether the triangle is filled. The program should create a triangle object with these sides and set the color and filled properties using the input. The program should display the area, perimeter, color and true or false to indicate whether it is filled or not.

My problem is that it's not outputting the area, perimeter, color and true or false to indicate whether it is filled or not. It just stops after the "Is the Triangle filled? 'True' or 'False'". Somebody help me please?

Triangle

    public class Triangle extends GeometricObject {

private double side1 = 1.0;
private double side2 = 1.0;
private double side3 = 1.0;

Triangle triangle = new Triangle(side1, side2, side3);

}

public Triangle(double side1, double side2, double side3) {
    this.side1 = side1;
    this.side2 = side2;
    this.side3 = side3;

    return side1;

public void setSide2(double side2) {
    this.side2 = side2;
}

public void setSide3(double side3) {
    this.side3 = side2;
}

public double getArea() {
    int p = (int) getPerimeter() / 2;
    return Math.sqrt(p * ((p - side1) * (p - side2) * (p - side3)));
}

public double getPerimeter() {
    return side1 + side2 + side3;

public String toString() {
return " Triangle: Side 1 = " + side1 + " Side 2 = " + side2

}

public java.util.Date getDateCreated() {
    return dateCreated;

    return "Created on " + dateCreated + "\n color: " + color + " and filled    ";

     }

TestTriangle

    import java.util.Scanner;

    public class TestTriangle  {

private double Side1 = 1.0;

public static void main(String[] args) {

    double Side3 = input.nextDouble();



    System.out.println("Enter the color of the Triangle");
    String color = input.next();


    System.out.println("Is the Triangle filled? 'True' or 'False' ");

    String filled = input.next(); 
}
{
    Triangle triangle = new Triangle(Side1, Side2, Side3);


    System.out.println("The Triangle Sides are \n side 1: " + triangle.getSide1() + "\n Side 2: " + triangle.getSide2() + "\n Side 3: " + triangle.getSide3());

        System.out.println("The Triangle's Area is " + triangle.getArea());

        System.out.println("The Triangle's Perimeter is " + triangle.getPerimeter());

        System.out.println("The Triangle's Color is " + triangle.getColor());
        System.out.println("Is the Triangle filled? " + triangle.isFilled());


        }
    }
