java中怎样实现线条的加粗最好有源代码，谢谢
！！！

Answer 1

如果是在图形编程中,可以使用BisicStroke(float width,int cap,int join);来实现
width表示线条的粗细,默认值为1;cap决定线条两端的形状,;join决定两段线条的连接样式.
可以参考下面的例子:
import javax.swing.*;
import java.awt.*;
import java.awt.geom.*;
public class DrawLine2D extends JFrame{
    public DrawLine2D(){
        super("");
        setSize(400,400);
        setVisible(true);
    }
    public void paint(Graphics g){
        Graphics2D g_2d=(Graphics2D)g;
        BisicStroke bs=new BisicStroke(2f,BisicStroke.CAP_BUTT,BisicStroke.JOIN_BEVEL);
        Line2D line=new Line2D.Double(20,60,200,60);
        g_2d.setColor(Color.BLUE);
        g_2d.setStroke(bs);
        g_2d.draw(line);
    }
    public static void main(String[] args){
        DrawLine2D drawLine2D=new DrawLine2D();
        drawLine2D.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    }
}

Answer 2

BisicStroke => BasicStroke

Answer 3

实现Stroke接口就可以了！！！
JAVA提供了个实现的子类BasicStroke
