Question

Any idea why the code below prints the numbers up and down instead of sideways?

They should print like this:

299 297 275 273 264   

260 253 247 242 234   

231 221 220 209 208   

Found 15 integers totaling 3733

Mine prints like this:

299
297
275
273
264

260
253
247
242
234

231
221
220
209
208

Number of multiples are: 15 The sum of multiples are: 3733

public static void main(String[] args) { //start of the main
        {
            int highestNumber = 300;
            int countOfNumbers = 0;
            int totalSum = 0;

            while (highestNumber >= 200) {
                if ((highestNumber % 11 == 0) && (highestNumber % 13 != 0)) {
                    System.out.println(highestNumber + "");
                    countOfNumbers++;
                    totalSum += highestNumber;
                    if (countOfNumbers % 5 == 0)
                        System.out.println();
                }
                if ((highestNumber % 13 == 0) && (highestNumber % 11 != 0)) {
                    System.out.println(highestNumber + "");
                    countOfNumbers++;
                    totalSum += highestNumber;
                    if (countOfNumbers % 5 == 0)
                        System.out.println();
                }
                highestNumber = highestNumber - 1;
            }
            System.out.println("Number of multiples are: " + countOfNumbers + " The sum of multiples are: " + totalSum);
        }
    }
}

It is solved by removing ln from println which prints a newline character. And also included space in both the print statements. (These have been commented for reference).

CODE

import java.util.*;

 // Compiler version JDK 11.0.2

 class Dcoder
 {
   
public static void main(String[] args) { //start of the main
        {
            int highestNumber = 300;
            int countOfNumbers = 0;
            int totalSum = 0;

            while (highestNumber >= 200) {
                if ((highestNumber % 11 == 0) && (highestNumber % 13 != 0)) {
                    System.out.print(highestNumber + " ");// remove ln from println
                                                          // and include space
                    countOfNumbers++;
                    totalSum += highestNumber;
                    if (countOfNumbers % 5 == 0)
                        System.out.println();
                }
                if ((highestNumber % 13 == 0) && (highestNumber % 11 != 0)) {
                    System.out.print(highestNumber + " ");// same editing here also 
                    countOfNumbers++;
                    totalSum += highestNumber;
                    if (countOfNumbers % 5 == 0)
                        System.out.println();
                }
                highestNumber = highestNumber - 1;
            }
            System.out.println("Number of multiples are: " + countOfNumbers + " The sum of multiples are: " + totalSum);
        }
    }
}
