In the public method called javax.swing.plaf.basic.BasicSliderUI.paintTrack(Graphics) there are assignments to local objects, but they are never used in the method.

    public void paintTrack(Graphics g) {
        int cx, cy, cw, ch;
        int pad; <---------------- local object, useless

        Rectangle trackBounds = trackRect;

        if ( slider.getOrientation() == JSlider.HORIZONTAL ) {
            pad = trackBuffer; <----------------- dead store
            cx = pad; // <----------------------- dead store
            cy = (trackBounds.height / 2) - 2;
            cw = trackBounds.width;

            g.translate(trackBounds.x, trackBounds.y + cy);

            g.setColor(getShadowColor());
            g.drawLine(0, 0, cw - 1, 0);
            g.drawLine(0, 1, 0, 2);
            g.setColor(getHighlightColor());
            g.drawLine(0, 3, cw, 3);
            g.drawLine(cw, 0, cw, 3);
            g.setColor(Color.black);
            g.drawLine(1, 1, cw-2, 1);

            g.translate(-trackBounds.x, -(trackBounds.y + cy));
        }
        else {
            pad = trackBuffer; // <------------- dead store
            cx = (trackBounds.width / 2) - 2;
            cy = pad; // <--------------------- dead store
            ch = trackBounds.height;

            g.translate(trackBounds.x + cx, trackBounds.y);

            g.setColor(getShadowColor());
            g.drawLine(0, 0, 0, ch - 1);
            g.drawLine(1, 0, 2, 0);
            g.setColor(getHighlightColor());
            g.drawLine(3, 0, 3, ch);
            g.drawLine(0, ch, 3, ch);
            g.setColor(Color.black);
            g.drawLine(1, 1, 1, ch-2);

            g.translate(-(trackBounds.x + cx), -trackBounds.y);
        }
    }
