如何将两个 for 循环的 Output 组合成“表格”格式？

Question

I used two for loops to convert miles to km and km to miles respectively for selected values. However the issue I am facing is that the output for the first for loop is not side by side with the output of the second table. Appreciate some help on this!

public static double miletoKilometer(double mile) {
 double conversion = mile * 1.609;
 return conversion;
}

public static double kilometerToMile(double km) {
 double conversion2 = km / 1.609;
 return conversion2;
}

public static void main(String[] args) {
 int mileInput = 0;
 double kmOutput = 0;
 int kmInput = 0;
 double mileOutput = 0;
 int displayRow1 = 0;
 int displayRow2 = 0;
 System.out.print("Miles\tKilometres\tKilometres\tMiles \n");

 for (int i = 0; i < 11; i++) {
  if (i == 1 || i == 2 || i == 9 || i == 10) {
   mileInput = i;
   System.out.printf("\n" + i);
   kmOutput = miletoKilometer(mileInput);
   System.out.printf("\t %.3f\n", kmOutput);
  }
 }
 for (int j = 0; j < 66; j++) {
  if (j == 20 || j == 25 || j == 60 || j == 65) {
   kmInput = j;
   System.out.printf("\n\t\t         " + j);
   mileOutput = kilometerToMile(kmInput);
   System.out.printf("\t\t%.3f", mileOutput);
  }

 }
}

Current Output: enter image description here

Changing your loop to match the code below should put everything in the right order. Not the most elegant solution but it gets the job done.

        int j = 0;
    for (int i = 0; i < 11; i++) {
        if (i == 1 || i == 2 || i == 9 || i == 10) {
           mileInput = i;
           System.out.printf("\n" + i);
           kmOutput = miletoKilometer(mileInput);
           System.out.printf("\t %.3f", kmOutput);
           for (; j < 66; j++) {
               if (j == 20 || j == 25 || j == 60 || j == 65) {
                 kmInput = j;
                 System.out.printf("\t\t         " + j);
                 mileOutput = kilometerToMile(kmInput);
                 System.out.printf("\t\t%.3f\n", mileOutput);
                 j++;
                 break;
              }
          }
        }
    }
