如何对逗号分隔的字符串进行排序？

Question

我有以下Ruby代码：

settings= hash.new
settings= batch.getPartialSettings
settings= batchSettings.merge(batch.getEntireSettings)
puts settings

结果是：

{"Resolution"=>"1024", "Applications"=>"Mozilla,IE,Chrome", "Programming"=>"Java,HTML"}

我希望将"Applications"排序为：

"Applications"=>"Chrome,IE,Mozilla" 

所以，我的最终结果应该是：

{"Resolution"=>"1024", "Applications"=>"Chrome,IE,Mozilla", "Programming"=>"Java,HTML"}

Answer 1

unsorted_apps = settings['Applications']
sorted_apps = unsorted_apps.split(',').sort.join(',')
settings['Applications'] = sorted_apps
