Question

I’m trying to draw curved lines in Java. A simple bezier curve with an (X,Y) start, an (X,Y) end, and a curve amount would suffice.

I can’t find a way to do this in Swing. If it’s not in Swing, is there some simple math I can use to do it? And how would I implement it in Swing?

Edit: I’m aware of how to draw shapes and lines by overriding the paint(Graphics g) method.

Answer 1

You can draw a Bézier curve using the Java 2D Object Path2D.Double. Just call the method curveTo(float x1,
float y1,
float x2,
float y2,
float x3,
float y3) and define the 3 coordinate.

• first Bézier control point
• second Bézier control point
• final end point
