Doubt in format and printf

[Ankit Dhebar]

Hello Can anyone please explain me the below code step by step otherwise It becomes difficult for me to understand.

int i1 = -123;
int i2 = 12345;
System.out.printf(">%1$(7d< \n", i1);
System.out.printf(">%0,7d< \n", i2);
System.out.format(">%+-7d< \n", i2);
System.out.printf(">%2$b + %1$5d< \n", i1, false);

Thanks !

Hi Ankit,

Your question is a little too broad. Have you tried running your code? If so, what specific things don't you understand?

To answer format questions first you should know the following.........

b boolean
n c char
n d integer
n f floating point
n s string


"-" Left justify this argument
n "+" Include a sign (+ or -) with this argument
n "0" Pad this argument with zeroes
n "," Use locale-specific grouping separators (i.e., the comma in 123,456)
n "(" Enclose negative numbers in parentheses

I do not believe ask anyone to explain the format and printf is a good idea, what you need to do is read the specification first and try to run the code yourself and memorise and understand the result.
