Instructions

Consider this data sequence: "fish bird reptile reptile bird bird bird mammal fish". Let's define a SINGLETON to be a data element that is not repeated immediately before or after itself in the sequence. So$,$ here there are four SINGLETONs $($the first appearance of "fish", the first appearance of "bird", "mammal", and the second appearance of "fish"$).$ Write some code that uses a loop to read a sequence of words, terminated by the $"$xxxxx$".$ The code assigns to the variable $n$ the number of SINGLETONs that were read. $($For example in the above data sequence it would assign $4$ to Assume that $n$ has already been declared. but not initialized. Assume that there will be at least one word before the terminating $"$xxxxx$".$

ASSUME the availability of a variable, stdin, that references a Scanner object associated with standard input.

Please write the code in java. Thank you!

Below is what I had from line $11-$line $34$

What's wrong with my code?
