Question

String Format

Asked by: Margin_Walker

Experts,

I am trying to format a String into fixed columns that appear to be in cells like below

system:     ice        calypso
id:              1234     5678
book:         ABC      XYZ


I can print this out nicely with the snippet of code attached but I need to save that output to a String so it can be used elsewhere.  When I save it as a string like so
MAIL_STRING = System.out.format(format, "System: ", "ICE" , "Calypso") + "\n";
it comes out with an output like this - java.io.PrintStream@c52200

Can you please help me save the correctly fomated String into a String variable?

Thanks

String format = "%1$-25s%2$-25s%3$-25s\n"; 
System.out.format(format, "System: ", "ICE" , "Calypso") + "\n";
System.out.format(format, "Id: ", iceCurrent.getId(), calTrade.getId()) + "\n";
System.out.format(format, "Book: ", iceCurrent.getBook(), calTrade.getBook()) + "\n";

use String.format instead of System.out.format

 

by: ozlevanonPosted on 2009-11-06 at 12:33:33ID: 25762790

Use String.format() method. It formats a string using a syntax format and args, and returns the result as String

> System.out.format(format, "System: ", "ICE" , "Calypso") + "\n";

get rid of the \n and store the result to a string

String formatted = System.out.format(format, "System: ", "ICE" , "Calypso");

same for the other 2

sorry scratch the bit about storing result to string

System.out.format(format, "System: ", "ICE" , "Calypso");

objects,

He does not have troubles with printing it; he needs to save it as a String :)

 

by: Margin_WalkerPosted on 2009-11-09 at 01:46:43ID: 31651205

Thanks guys, you both gave me the correct answer at the exact same time!

Objects, your suggestion was what I had in place already and was producing junk output for me.  Thanks anyway!
