如何清除applet中已经画好的矢量图或者图片
程序代码：
import java.applet.*;
import java.awt.*;
public class DrawingLines extends Applet {
int width, height;
public void init() {
width = getSize().width;
height = getSize().height;
setBackground( Color.black );
}
public void paint( Graphics g ) {
g.setColor( Color.green );
for ( int i = 0; i < 10; ++i ) {
g.drawLine( width, height, i * width / 10, 0 );
}
}
}
比如上面一个很简单的applet，画好了直线，我想要再相应的一段时间之后清除所有applet画板上面所有画好的矢量图或者是图片而能重新开始绘画新的图。请问如何？谢谢
import java.awt.*;
public class DrawingLines extends Applet {
int width, height;
public void init() {
width = getSize().width;
height = getSize().height;
setBackground( Color.black );
}
public void paint( Graphics g ) {
g.setColor( Color.green );
for ( int i = 0; i < 10; ++i ) {
g.drawLine( width, height, i * width / 10, 0 );
}
}
}
