Printline coordinating

Question

As of now I have this piece of code:
System.out.println("ACTIVE RULES: \t\t\t AVAILABLE COMMANDS: ");
                        int n = 25 - str.length();
                  String ws= " ";
                  String ws_new = "";
                  for (int j=0; j<n; j++){
                       ws_new = ws_new.concat(ws);
                  String value = comm.get(str);
                  System.out.println(str+ws_new+"\t"+value);
        }So fist this Act. Rules and Av. Commands is printed, with some tabs in between, and then below the corresponding stuff is printed, with the idea to create some table which displays it nice and clearly. That's where the for loop comes in, to let the right column of the table start at the same point all the time. So because the placing of the "value" depends on the length of "str" (length of "str" plus one tab), and I want the placing of value on the line to be independant of it, which it is now.
I find this 25-str.length() and the loop a bit exaggerated to fix this though and was just wondering if there is no more efficient way of doing it?
Not that it's really a performance issue or whatever, but I'm just wondering...

Hi,
Instead of a for loop you could try something like
while (ws_new.length() < 25) {
         //increase length of ws_new
}Also it might be more efficient if you use a StringBuffer rather than a String...
Just some ideas.
