Question

Here’s a quote from: http://docs.oracle.com/javase/1.5.0/docs/api/java/util/Formatter.html

‘d’ ‘\u0054’ Formats the argument as a decimal integer. The
localization algorithm is applied.

If the ‘0’ flag is given and the value is negative, then the zero padding will occur after the sign.

I feel frustrated, trying to learn this formatting thing but that tutorial is just so cluttered and messy.

String.format("%03d", int); 

I am trying to understand where exactly this whole \u0054 should go but I have just no idea, I must be missing something very obvious or something…

Edit:

What I want to achieve:
Positive 10: 010
Negative 10: -10
Negative result I want to achieve: -010

Answer 1

\u0054 is d

You can do

((i < 0) ? "-" : "") + String.format("%03d", Math.abs(i));
