  • Method Details

    • contains

      public boolean contains(Vector2D point)
      Description copied from interface: Shape
      Checks if this Shape contains a point.
      Specified by:
      contains in interface Shape
      Parameters:
      point - the point to check
      Returns:
      true if this shape contains the point

    • points

      public Vector2D[] points()
      Specified by:
      points in interface Shape
      Returns:
      the array of points making up this shape

    • getArea

      public float getArea()
      Description copied from interface: Shape
      Calculates the area of this shape and return it.
      Specified by:
      getArea in interface Shape
      Returns:
      the area of this shape

    • toString

      public final String toString()
      Returns a string representation of this record class. The representation contains the name of the class, followed by the name and value of each of the record components.
      Specified by:
      toString in class Record
      Returns:
