`static void`	`line(int x1, int y1, int x2, int y2)` draws a line from (x1, y1) to (x2, y2)
`static void`	`open()` opens the window with its default size
`static void`	`open(int w, int h)` opens the window with width w and height h
`static void`	`rectangle(int x, int y, int w, int h)` draws a rectangle at (x, y) with width w and height h
`static void`	`text(java.lang.String text, int x, int y)` draws a text with left-bottom corner (x, y)
