Write a public static method named allDuplicates that will take an ArrayList$=\{1,2,3,4,5\}\{3,2,3,1,4,2,1,3,0\}\{3,2,1\}\{1,1,1\}\{1\}>()$; with these values $\{1,1,1\}$; allDuplicates $(myList)$ should return $an$ ArrayList with these values $\{1\}$

Helpful Info:$>$ with these values $\{3,2,1\}$

Example $3$

Given: ArrayList myList $=$ new ArrayList$>()$; with these values $\{1,1,1\}$; allDuplicates $(myList)$ should return $an$ ArrayList with these values $\{1\}$

Helpful Info:$>()$; with these values $\{3,2,3,1,4,2,1,3,0\}$; allDuplicates $(myList)$ should return $an$ ArrayList$>$ with these values $\{3,2,1\}$

Example $3$

Given: ArrayList myList $=$ new ArrayList$>()$; with these values $\{1,1,1\}$; allDuplicates $(myList)$ should return $an$ ArrayList with these values $\{1\}$

Helpful Info:$>()$; with these values $\{1,2,3,4,5\}$;

allDuplicates $(myList)$ should return $an$ ArrayList with these values $\{\}$

Example $2$

Given: ArrayList myList $=$ new ArrayList$>()$; with these values $\{3,2,3,1,4,2,1,3,0\}$; allDuplicates $(myList)$ should return $an$ ArrayList$>$ with these values $\{3,2,1\}$
