Need help formatting output

Hey all here is my code:

Code:

---

public static void main(String [] args){
               
                System.out.println("Feet \tMeters");
               
                for(int i=1;i<=10;i++){
                        double foot =i;
                        System.out.print(" "+foot);
                        System.out.printf("\t  "+"%.2f\n",footToMeter(foot));
        }
               
                System.out.println();
                System.out.println("Meters \t  Feet");
               
                for(int i=20;i<=65;i+=5){
                        double meter =i;
                        System.out.print("  "+meter);
                        System.out.printf("\t  "+"%.2f\n",meterToFoot(meter));
                }
               
        }
       
        public static double footToMeter(double foot){
               
                double meter = 0.305*foot;
                return meter;
               
        }
       
        public static double meterToFoot(double meter){
                double foot = meter/.305;
                return foot;
        }

---

Here is the output:

Code:

---

Feet        Meters
 1.0          0.31
 2.0          0.61
 3.0          0.92
 4.0          1.22
 5.0          1.53
 6.0          1.83
 7.0          2.14
 8.0          2.44
 9.0          2.75
 10.0          3.05

Meters            Feet
  20.0          65.57
  25.0          81.97
  30.0          98.36
  35.0          114.75
  40.0          131.15
  45.0          147.54
  50.0          163.93
  55.0          180.33
  60.0          196.72
  65.0          213.11

My problem is I want the numbers under Feet to line up so it would look like this (move 10.0 over somehow):

Code:

---

Feet        Meters
 1.0          0.31
 2.0          0.61
 3.0          0.92
 4.0          1.22
 5.0          1.53
 6.0          1.83
 7.0          2.14
 8.0          2.44
 9.0          2.75
10.0          3.05

---

Also I need it to line up under the second Foot column like this:

Code:

---

Meters            Feet
  20.0          65.57
  25.0          81.97
  30.0          98.36
  35.0          114.75
  40.0          131.15
  45.0          147.54
  50.0          163.93
  55.0          180.33
  60.0          196.72
  65.0          213.11

How would I do this? Thanks for any help and sorry for the long post.

Easy way is to check if the number is less than 10, prepend a space. If it is less than 100, prepend another space. Etc.

Okay yeah I see what your saying is there no formatting tool or feature that kicks it over to the left instead of the right built in to java?

Put a field width modifier after the % sign. In your example, try 6. But read up about how it works in Formatter (Java Platform SE 7 )

Not necessary! It can be done with Formatter class.

Regards,
Jim

java - Formatting numbers with same amount of padding - Stack Overflow

Can specify a width

Code:

---

public static void main(String args[])
{
        String format = "%10.2f\n"; // width == 10 and 2 digits after the dot
        float[] floats = { 123.45f, 99.0f, 23.2f, 45.0f };
        for(int i = 0; i < floats.length; i++)
        {
                float value = floats[i];
                System.out.format(format, value);
        }
}

Okay thanks Jim I ended up using a %4.1f and a %6.2f

Code:

---

        public static void main(String [] args){
               
                System.out.println("Feet \t  Meters");
               
                for(int i=1;i<=10;i++){
                        double foot =i;
                        System.out.printf("%4.1f",foot);
                        System.out.printf("\t  "+"%6.2f\n",footToMeter(foot));
        }
               
                System.out.println();
                System.out.println("Meters \t    Feet");
               
                for(int i=20;i<=65;i+=5){
                        double meter =i;
                        System.out.print("  "+meter);
                        System.out.printf("\t  "+"%6.2f\n",meterToFoot(meter));
                }
               
        }
       
        public static double footToMeter(double foot){
               
                double meter = 0.305*foot;
                return meter;
               
        }
       
        public static double meterToFoot(double meter){
                double foot = meter/.305;
                return foot;

Thanks again
