Java - How can I output the following statement as a single line with a newline? Program below. import java.util.Scanner; public class LabProgram { public static void main(String[] args) { Scanner sc = new Scanner(System.in); int n = sc.nextInt(); if(n>=11 && n<=100) { while(n>=11 && n<=100) { System.out.print(n+ " "); (the problem line. When I use System.out.println, it makes the line vertical when I want it horizontal.) if(n ==11||n==22||n==33||n==44||n==55||n==66||n==77||n==88||n==99) break; n--; } } else System.out.println("Input must be 11-100"); }}
