TreeSet

Given variables$\backslash ($a$,$b$,$c$\backslash ),$and$\backslash ($d$\backslash ),$perform the following steps:

$-$Declare a TreeSet of Integer called numbers.

$-\backslash (\backslash$quad$\backslash )$Use a method to add each value from the provided variables$\backslash ($a$,$b$,$c$\backslash ),$and$\backslash ($d$\backslash )$to the numbers TreeSet.

$-$Print the elements of the TreeSet numbers to the console, preceded by the string "Before:$"$in your print statement.

$-\backslash (\backslash$quad$\backslash )$Use the clear$()$method to remove all the elements from the TreeSet called numbers.

$-$Print the elements again after the TreeSet numbers is cleared. Add the string "After:$"$to the beginning of your print statement
