Examples of java.awt.Graphics.drawLine()

java.awt.Graphics.drawLine()
Draws a line, using the current color, between the points (x1, y1) and (x2, y2) in this graphics context's coordinate system. @param x1 the first point's x coordinate. @param y1 the first point's y coordinate. @param x2 the second point's x coordinate. @param y2 the second point's y coordinate.
