Question about the task Remove duplicate strings
Java Syntax, Level 6, Lesson 4
Resolved
Can't pass second check and a bug?The program seems to work. It will replace duplicates with null. Unless it refers to itself, then it continues. If I use Scanner.nextLine, it will end and display my results once I enter the 4th word, "Java". The only way I can enter more words is if I put something below it like a System.out.print

I need a little help...I feel a little embarrassed to ask, due to the simplicity of the problem, yet my code isn't working and I can't figure out why. It's printing the opposite of what I want it to print. I ask it to print a string 4 times, it prints it 2 times, and vice-versa. Can anyone help me. Thank you!
