Printf question

[Anu Bhagat]

Hi ,
The following code prints
1213%1$s

I understand the 1213 portion of the output, but don't undersatnd the rest of the output. Please expain. I read the Java Language documentation but don't get it.

Thanks in advance.

class PrintfTest {
      public static void main(String args[]){
               System.out.printf("12%1$s","13%1$s","14%1$s");
       }
}

Anu,

There is only a format string in the call: "12%1$s". This simply constructs a string with the contents "12" plus the first argument in the argument list using string conversion (basically, creates a string which is "12" concatenated with the second argument of the printf() call.)
