one question about printf()

[icepeanuts]

I tried the code below. The result is "hell". But I do not understand why. Could anyone help me out? Thanks.

System.out.printf("%3.4s\n", "hello world");

It is quite straight forward. Please go through this: http://web.cerritos.edu/jwilson/SitePag ... erence.pdf
Please check how width and precision work for strings.
