You need to keep printing space in inner loop and once it come out from the inner loop print * and/or # accordingly. Scanner in = new Scanner(System.in); int x=0; System.out.println(“Enter number: “); x = in.nextInt(); for(int i=1;i<=x;i++){ for(int j=1;j<=i;j++){ System.out.print(” “); } if(i%2==1) { System.out.println(“*”); }else { System.out.println(“#”); } } >>>Demo Link<<< 0 solved … Read more
If I understand correctly your Scanner is breaking on spaces. You want it to break on new lines: Scanner scanner = new Scanner(System.in); scanner.useDelimiter(System.getProperty(“line.separator”)); // this scans for lines while (scanner.hasNext()) { String input = scanner.next(); System.out.println(input); // take a look for yourself } 4 solved I have an issue using tokens, scanning multiple inputs … Read more
