Create a table and put data inside

How can I create a table for this code?

The table would show the n and the result.

Something that would look like

I know I can print it using System.out.print(.....) but it there a better way to do it?

      fib(n)   result
        9        34
        10       55
        11       89
      

class fib
{
    static int fib(int n)
    {
        int f[] = new int[n+2]; 
        int i;

    
        f[0] = 0;
        f[1] = 1;

        for (i = 2; i <= n; i++)
        {
            f[i] = f[i-1] + f[i-2];
        }

        return f[n];
    }

    public static void main (String args[])
    {
        int a = 9;
        int b = 10;
        int c = 11;
        System.out.println(fib(a));
        System.out.println(fib(b));
        System.out.println(fib(c));


    }
} 

Right now your code only outputs the results of the fib method. The println method outputs the data you specify as parameter, and then ends the line.

In addition to println, the PrintStream class has many methods that allow you to do specific things with outputting text. One method you could use is print, which does the same as println but does not end the line. This means you can do:

System.out.print("\t"); // Print a tab character
System.out.print(a); // Print variable a
System.out.print("\t"); // Print another tab character
System.out.println(fib(a)); // Calculate fib(a), print the result, and end the line

Another interesting method is printf, which allows you to specify a "format String", that then gets populated with the values of the additional parameters passed to the method.

System.out.printf("\t%d\t%d%n", a, fib(a)); // Output the variable a and result of fib(a), and end the line

Format Strings are a pretty broad subject, but the above example specifies that two tabs should be printed, with a decimal (%d) after the first tab and another one (the second %d) after the second tab. The next parameter (a) replaces the first decimal, the second parameter (the result of fib(a)) replaces the second decimal. The %n means "end the line".

You can output the header in a similar manner.
