You can use the Stream. distinct() method to remove duplicates from a Stream in Java 8 and beyond. The distinct() method behaves like a distinct clause of SQL, which eliminates duplicate rows from the result set.
You can easily clear the content of a StringStream object by using the predefined ss. clear() function. The function will erase the data in the buffer and make the object empty.
The consecutive duplicates of the string can be removed using the unique() function provided in STL.
What you're doing is clearing the string that is returned from the stringstream, not the internal string. You'll have to actually do the ss.str("")
