Explain the Stroke Line Join property of 2D shapes in JavaFX

In shapes formed by joining more than one line, the stroke line join property specifies/defines the shape of the joint of the two lines. You can set the stoke line join using the setStrokeLineJoin() method.

Java FX supports three kinds of stroke line joins represented by three constants of the Enum named StrokeLineJoin they are −

• BEVEL − In this type, the outside edges of the intersection are connected with a line segment.

• MITER − In this type, the outside edges of the intersection are joined together forming a sharp edge.

• ROUND − In this type, the outside edges of the intersection are joined by rounding off the corner, the radius of this will be exactly half the width of the join.

Example
