testgraphics.java

主要是对于JAVA的编程的基本语言 希望能够帮得上你。

package ForTest;

import java.applet.*;
import java.awt.*;
import java.awt.geom.*;

public class TestGraphics extends Applet{
	
	public void paint(Graphics g){
		this.setSize(400,700);
		g.drawRoundRect(10, 10, 100, 100, 50, 50);
		g.drawRoundRect(10, 120, 100, 100, 50, 100);
		g.drawRoundRect(10, 240, 100, 100, 100, 50);
		g.draw3DRect(10, 350, 100, 100,true);
		g.setColor(Color.YELLOW);
		g.fill3DRect(10, 460, 100, 100,true);
		//g.fillRect(10, 460, 100, 100);
		g.setColor(new Color(255,0,0));
		g.drawArc(200,100,120,120,90,180);
		g.fillArc(200,100,120,120,30,300);
		
		int[] px1={50,90,10,50};
		int[] py1={10,50,50,30};		
		g.drawPolygon(px1,py1,4);
		
		
		Graphics2D g2d=(Graphics2D)g;
		BasicStroke bs=new BasicStroke(10,BasicStroke.CAP_ROUND,
				BasicStroke.JOIN_MITER);
		g2d.setStroke(bs);
		Line2D line1=new Line2D.Double(20,30,150,130);
		Line2D line2=new Line2D.Double(120,30,20,30);
		g2d.draw(line1);
		g2d.setColor(Color.BLACK);
		g2d.draw(line2);
		
		GradientPaint gp=new GradientPaint(200,100,Color.RED,
				400,300,Color.BLACK);
		g2d.setPaint(gp);
		Arc2D circle=new Arc2D.Double(250,150,150,150,0,360,Arc2D.OPEN);
