change nextLine() to nextInt() also delete public int x {} as you have already initialized int x to scanner

nextLine() reads the remainder of the current line even if it is empty. nextInt() reads an integer but does not read the escape sequence "\n". But dont worry too much about this just know nextInt() is for int's and nextLine() is for Strings.
