Draw faster rectanglesTag(s): AWT
Thanks to Chikirev Sergey
It seems that drawRoundRect(.) is 1,5 faster then drawRect(..) , because one of them is completely native.
import java.awt.*; import java.awt.event.*; public class Class1 extends Frame implements ActionListener{ public void paint(Graphics g){ super.paint(g); long t=System.currentTimeMillis(); for(int i=0;i<10000;i++){ g.drawRect(10,70,100,50); } t=System.currentTimeMillis()-t; g.drawString(String.valueOf(t),10,70); t=System.currentTimeMillis(); for(int i=0;i<10000;i++){ g.drawRoundRect(10,130,100,50,0,0); } t=System.currentTimeMillis()-t; g.drawString(String.valueOf(t),10,130); } public void actionPerformed(ActionEvent p1){ repaint(0,10,200,300); } public static void main (String[] args){ Class1 c=new Class1(); c.setSize(300,300); c.setLayout(new BorderLayout()); Button b=new Button("Refresh"); c.add(BorderLayout.SOUTH , b); b.addActionListener(c); c.show(); } }
