How do I insert an image into my Java applet?
提问by Boxwood
Basically I have to write a Java applet that produces a business card. The part I'm stuck on is figuring out how to display an image of myself in the applet.
基本上，我必须编写一个生成名片的 Java 小程序。我坚持的部分是弄清楚如何在小程序中显示我自己的图像。
The part I'm confused about in my directions is that it says:
我对我的方向感到困惑的部分是它说：
This assumes you have an image in the directory of your BlueJ project called 'businesscard.jpg'
这假设您在 BlueJ 项目的目录中有一个名为“businesscard.jpg”的图像
How do I get my picture into the directory of my BlueJ project even? How do I then get the code the right way so it appears in the applet?
我如何将我的图片放入我的 BlueJ 项目的目录中？然后我如何以正确的方式获取代码，使其出现在小程序中？

page.fillOval (MID, TOP, 60, 60); //bottom half of the trophy. the rounded part.
page.drawArc (MID-8, TOP+15, 25, 25, 100, 160); //left arc
page.drawArc (MID+43, TOP+15 , 25, 25, 280, 160); //right arc
page.fillRect (MID+1, TOP+1, 59, 25); //make the top of the trophy flat basically
page.fillRect (MID+22, TOP+60, 15, 25); //neck of the trophy
page.drawLine (MID+48, TOP+84, MID+10, TOP+84); //base of the trophy
page.setColor (Color.blue);
Font i = new Font("serif", Font.BOLD, 20);
page.setFont(i);
page.drawString ("#1", MID+20, TOP+30); //Creates the "#1" on the trophy.
//The following is all code for inserting my image
BufferedImage photo = null;
try {
URL u = new URL(getCodeBase(), "businesscard.jpg");
photo = ImageIO.read(u);
} catch (IOException e) {
page.drawString("Problem reading the file", 100, 100);
}
page.drawImage(photo, 10, 10, 150, 225, null);
}
}
