Today I came across a thing, is it possible to change the Standard Output Stream?
Then I immediately went for assign the System.out variable. -
System.out = new PrintStream(new File("some_file_name"));
-
Then I got a message, the final variable not to be updated.
Then I came to know that I have to take help from API, - System.setOut(new PrintStream(new File("")))
So how Java updates the System.out as it's final.
Please help me to know it.
Kind regards,
Dmjpro.

Java does not change the System.out at all.
What makes you think that it changes it?

Duh, that System class is full of native methods and stuff; it even uses a
sun.misc.Shared Secrets class for several purposes; I don't trust that class
one single bit ;-)

Yup; check your src.zip that comes with the jdk; that class is full of it.

I'm sticking with 1.5 for my current project.
I'd like to find time and look to see what those guys were doing with a secrets class though.

They don't want us to know that, it's a class in the sun.misc package and they
don't give source for any class in those packages; they're 'SharedSecrets' .

It doesn't matter much: real men (like me) read octal or hex dumps anyway ;-)

Oh yeah, there is always a legal way of reconstructing someone's source code even though the source code is supposed to be "private".

I'd like to create a "custom output facility". In other words, I want
an object whose use is similar to std::cout/std::cerr, but offers more
flexibility. Instead of simply writing the parameter to stdout/stderr,
I'd like it to write to stdout, to a file, and/or call a logging
function.
So my output function might look something like this:
OutputFacility& OutputFacility::put(const std::string& s) {
cout << s; // print to stdout

I haven't looked very closely, but from what I'm seeing, it looks like there

like a cache that can hold data from the source, or for the destination
that can't be immediately processed. Say, for example, if you are...

I have huge number of legacy code which use standard files functions.
I would like to pass a memory pointer rather than a FILE pointer.

I do not want to touch the legacy code. Does any one know of a library

Hello,
I am writing some code in the scenario which can be described as follow:
+ program A which writes to standard output (e.g. cout >> whatever).
+ program B which has GUI and also listens to the standart input regularly (using a timer) if there is no input, it returns to the GUI and does something else.
What I expect is B should work without problem in both cases:
(1) user@host $ A | B
(2) user@host $ B
In B's code, I tried...

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
