# Princeton Standard Libraries Jruby wrapper

I was going through the [Algorithms 4th edition](https://algs4.cs.princeton.edu/home/) and wanted to write the algorithms in ruby instead of the default java. The book uses the [Princeton Standard Libraries](https://introcs.cs.princeton.edu/java/stdlib/) to help clarify the code.

## Installation

Add this line to your application's Gemfile:

```ruby

gem 'princeton_standard_libraries'

```

And then execute:

    $ bundle

Or install it yourself as:

    $ gem install princeton_standard_libraries

## Usage

    require 'princeton_standard_libraries'

    

    n = 50

    Java::StdDraw.set_xscale(0,n)

    Java::StdDraw.set_yscale(0,n*n)

    Java::StdDraw.pen_radius = 0.01

    

    1.upto(n) do |i|

      Java::StdDraw.point(i, i)

      Java::StdDraw.point(i, i*i)

      Java::StdDraw.point(i, i*Math.log(i))

    end
