How can I restore the standard move in the BasicStroke class?

I have a program in which I have defined a bunch of new dash patterns and dabbed them with a class BasicStroke

. What I used .setStroke()

and make lines with my dashes. Now I want to be able setStroke()

to revert to the default silence pattern (solid line). How should I do it? Here is my code:

    float[] dash1 = {2f, 0f, 2f};
        float[] dash2 = {1f, 1f, 1f};
        float[] dash3 = {16f, 10f, 4f, 10f};
        float[] dash4 = {4f, 4f, 1f};

        Graphics2D g2d = (Graphics2D) g.create();
        g2d.drawLine(20, 40, 250, 40);

        BasicStroke bs1 = new BasicStroke(1, BasicStroke.CAP_BUTT,
                BasicStroke.JOIN_ROUND, 1.0f, dash3, 0f);

        BasicStroke bs2 =new BasicStroke(1, BasicStroke.CAP_BUTT,
                BasicStroke.JOIN_ROUND, 1.0f, dash3, 16f);

        BasicStroke bs3 = new BasicStroke(1, BasicStroke.CAP_BUTT,
                BasicStroke.JOIN_ROUND, 1.0f, dash3, 2f);

        BasicStroke bs4 = new BasicStroke(1, BasicStroke.CAP_BUTT,
                BasicStroke.JOIN_ROUND, 1.0f, dash4, 2f);



        g2d.setStroke(bs1);
        g2d.drawLine(20, 80, 250, 80);

        g2d.setStroke(bs2);
        g2d.drawLine(20, 120, 250, 120);

        g2d.setStroke(bs3);
        g2d.drawLine(20, 160, 250, 160);

        g2d.setStroke(bs4);
        g2d.drawLine(20, 200, 250, 200);
