Question

怎样设置画好的圆的颜色，求java代码

Answer 1

重画最好, 你不放源码, 具体该怎么做也不知道

追问

public void paint(Graphics g){
Graphics2D g2D = (Graphics2D)g;
Insets insets = getInsets();
int L = insets.left/2,T = insets.top/2;
h = getSize().height;
g.setColor(Color.white);

/
g.setFont(new Font("SansSerit",Font.BOLD,12));
g.drawString(" this is our clock",200,100);

追答

public class MyPanel extends Panel {
private int r;
private Color color;

public void paint(Graphics g){
g.setColor(color);
int h = this.getHeight();
int w = this.getWidth();
g.fillOval(w/2 - r, h/2 - r, 2 * r, 2 * r);
}

public Color getColor() {
return color;
}
public void setColor(Color color) {
this.color = color;
}
public MyPanel(int r){
this.r = r;
this.setBackground(Color.green);
}

public int getR() {
return r;
}
public void setR(int r) {
this.r = r;
}
}

这段代码是根据半径r 和 颜色来画一个圆
就是设置了成员变量r 和 color
如果你有一个MyPanel的实例 jp
jp.setColor(Color.red);
jp.repaint();
就是用红色画了个圆, 相当于改变了圆的颜色
