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

Question about why it doesn't work.So I know it's wrong but curious about exactly why please explain. I know we're supposed to create a new Thread object which then passes the new SpecialThread as an argument but I don't understand why we break from our standard initializing procedure of ObjectType variableName = new ObjectOfObject

Is the use of Random causing the conditions not to be met?The program works as expected, but does not meet the 6th and 7th requirements somehow. Is this because I used a Random object for the new Star(x, y) parameters?

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!
