如何在java中绘制自定义圆角矩形？

我知道如何绘制圆角矩形，但我想分别为每个角定义圆度，并绘制如下图所示的内容：

可能有几种方法可以实现这一点，但我能想到的最简单的方法是，正如安德鲁已经暗示的那样，将是定义自己的Shape

 import java.awt.Dimension; import java.awt.EventQueue; import java.awt.Graphics; import java.awt.Graphics2D; import java.awt.RenderingHints; import java.awt.geom.Path2D; import javax.swing.JFrame; import javax.swing.JPanel; import javax.swing.UIManager; import javax.swing.UnsupportedLookAndFeelException; public class SimpleShape { public static void main(String[] args) { new SimpleShape(); } public SimpleShape() { EventQueue.invokeLater(new Runnable() { @Override public void run() { try { UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName()); } catch (ClassNotFoundException | InstantiationException | IllegalAccessException | UnsupportedLookAndFeelException ex) { ex.printStackTrace(); } JFrame frame = new JFrame("Testing"); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); frame.add(new TestPane()); frame.pack(); frame.setLocationRelativeTo(null); frame.setVisible(true); } }); } public class TestPane extends JPanel { private RightEnd rightEnd; public TestPane() { rightEnd = new RightEnd(100, 100, 40); } @Override public Dimension getPreferredSize() { return new Dimension(100, 100); } @Override protected void paintComponent(Graphics g) { super.paintComponent(g); int x = (getWidth() - 100) / 2; int y = (getHeight()- 100) / 2; Graphics2D g2d = (Graphics2D) g.create(); g2d.setRenderingHint(RenderingHints.KEY_ANTIALIASING, RenderingHints.VALUE_ANTIALIAS_ON); g2d.translate(x, y); g2d.fill(rightEnd); g2d.dispose(); } } public class RightEnd extends Path2D.Float { public RightEnd(float width, float height, float radius) { moveTo(0, 0); lineTo(width - radius, 0); curveTo(width, 0, width, 0, width, radius); lineTo(width, height - radius); curveTo(width, height, width, height, width - radius, height); lineTo(0, height); closePath(); } } }
