Package: java-gcj-compat-dev
Version: 1.0.78-1
Severity: important
Hi.
I am trying to learn the Java Programming Language and, trying to get
formatted string to work (which I miss severely, as I am familiar with
them with C), I get nothing in the output of my program.
Here is what I have:
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
rbrito@chagas:/media/STORAGE/programming/java$ javac -source 1.5 Build.java
rbrito@chagas:/media/STORAGE/programming/java$ cat Build.java
import java.util.Locale;
import java.util.Formatter;
public class Build {
public static void main(String args[]) {
StringBuilder sb = new StringBuilder();
Formatter formatter = new Formatter(sb, Locale.US);
formatter.format("PI = %12.10f", Math.PI);
System.out.println(formatter);
}
}
rbrito@chagas:/media/STORAGE/programming/java$ java Build
PI =
rbrito@chagas:/media/STORAGE/programming/java$
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
The result here is not exactly what I expected, as it would be expected
to print pi to 10 decimal places. I took the example code above from
IBM's site developerworks, from an article entitled "Taming T iger:
Formatted output", from 02 Apr 2004.
If this code is wrong, then, please let me know and I will inform IBM.
Otherwise, it would be a good thing to include in the regression suite
of the Free Java implementations (actually, I only started considering
using Java once I knew that it was reasonably feature complete with a
Free implementation).
BTW, if I, OTOH, choose to install the non-free Sun Java JDK (and then
choosing it with update-alternatives), the very same bytecodes give me
the expected result (without any need to recompile, which means that the
Eclipse compiler seems to be generating correct/acceptable code):
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
rbrito@chagas:/media/STORAGE/programming/java$ java -version
java version "1.6.0_06"
Java(TM) SE Runtime Environment (build 1.6.0_06-b02)
Java HotSpot(TM) 64-Bit Server VM (build 10.0-b22, mixed mode)
rbrito@chagas:/media/STORAGE/programming/java$ java Build
PI = 3.1415926536
rbrito@chagas:/media/STORAGE/programming/java$
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
Please, help, as I want to get rid from non-free software.
Thanks in advance, Rogério Brito.
