Thread: Output in columns

Hi,

Any way i can format this output into columns?

for(int i = 0; i < 5; i++) {
    System.out.println(t[i]+n[i]+s[i]);
 }

Best Regards

Look into System.out.prinf().

Just outputs all messed up o.O

I did, but when I use them, all i get is the t[i] written in a line :/

for(int i = 0; i < 5; i++) {
            System.out.printf(title[i],"%20s", name[i], "%20s",subAmounts[i]);
       }

Alright, that clears some things up. That isn't quite the correct way to use printf()'s formatting capabilities. The basic syntax would be:
System.out.printf("format string", data1, data2, data3.....);
And this is what you are trying
System.out.printf(data1, "format string", data2, "format string", data3);
It should be noted that all formating information will be contained in the first argument for printf.

and would this work, if t[i] are Strings of different lengths? What is happening, is that my output is shifting here and there.

This is the Format string i used: String formatString = " %-15s %20s %20.1f %n";

Your format string, as it stands, creates a 15 character left justified column(type string); a 20 character right justified column (type string); then another 20 character right justified column (type float); last a new line (basically). If there are different lengths then you want to make the column big enough to accomodate the largest length, plus some for a bit of padding if the next column is also left justified which is probably what you want.

thanks man, I got it, I always used to find formatting a bitch heh.

Thanks
