Horizontal Ruler

Problem Description:

a recursive solution to printing an English Ruler with adjustable lengths

and number of tick marks. It produced output vertically, like this:

see image

Ruler of length $3$ with major tick length $3$

For this program, you are to print out rulers horizontally, like this:

see image

Notes:

You must start with the code we went over in class: Ruler.java

Your solution must be recursive

Your output must include your name.

Your program should run the three test cases that are already in Ruler.java

Ruler.java:

public class Ruler $\{$

public static void drawRuler$($int nInches, int majorLength$)\{$

drawLine$($majorLength$,0)$; $//$ draw inch $0$ line and label

for $($int j $=1$; j nInches; j$++)\{$

drawInterval$($majorLength $-1)$; $//$ draw interior ticks for inch

drawLine$($majorLength$,$ j$)$; $//$ draw inch j line and label

$\}$

$\}$

private static void drawInterval$($int centralLength$)\{$

if $($centralLength $>=1)\{//$ otherwise, do nothing

drawInterval$($centralLength $-1)$; $//$ recursively draw top interval

drawLine$($centralLength$)$; $//$ draw center tick line $($without label$)$

drawInterval$($centralLength $-1)$; $//$ recursively draw bottom interval

$\}$

$\}$

private static void drawLine$($int tickLength, int tickLabel$)\{$

for $($int j $=0$; j $$ tickLength; j$++)$

System.out.print$("-")$;

if $($tickLabel $>=0)$

System.out.print$(""+$ tickLabel$)$;

System.out.print$("$

$")$;

$\}$

private static void drawLine$($int tickLength$)\{$

drawLine$($tickLength$,-1)$;

$\}$

public static void main$($String$[]$ args$)\{$

System.out.print$("$

Ruler of length $2$ with major tick length $4$

$")$;

drawRuler$(2,4)$;

System.out.print$("$

Ruler of length $1$ with major tick length $5$

$")$;

drawRuler$(1,5)$;

System.out.print$("$

Ruler of length $3$ with major tick length $3$

$")$;

drawRuler$(3,3)$;

$\}$
