Re: Help me to figure out how code working
i don't think this code is correct. And regardless, using bitwise operators (&, | etc. ) only really makes sense if you are actually interested in individual bits.
Seems like the assignment here is...
Re: Tutorials code not working with variables and arrays
Makes sense. But I vaguely remember, from long ago, that in a class definition you could use
static
{
// arbitrary code here
}
for code to be executed at class load time.
Re: Cannot load file from resource using getClass().getResource
(Assuming this is on Windows) I like to use SysInternals Process Monitor to see where a program looks for its files. It can sometimes be surprising 😀
[EDIT] Oops, I read this is on Ubuntu. Then use...
Re: Solve my problem
An alternative title for this post could be "Do my work for me".
Re: Old programmers never die, they just become object oriented. (?)
Absolutely ! Same here. I think programming (as well as making music, my other hobby) will do wonders for the aging brain.
Re: Struggling with Java :o
I learnt Java 25 years ago from David Flanagan's book "JAVA in a nutshell" (published by O'Reilly) and found it eminently useful. Probably very outdated now, but to learn the basics, it might still...
Re: Struggling with generics
Awesome, that does it. Many thanks !!!
Re: Var ends up being 0
Well spotted by armela.
But why are you passing a and b as parameters to function additionate(), but not to function storeInMap() ? This is so inconsistent. Either pass your variables down to...
Re: Are method parameters two way traffic?
No, as explained by Norm. And even if you could, it would be very bad design. Nobody expects a method to have side effects in code outside the method, let alone mess with variables defined on a...
Re: Struggling with generics
Good tip Norm, thanks. I don't like suppressing warnings, but fixing them all in the code is getting like a huge pain in the butt. And I admit I WAS compiling with -Xlint:unchecked (after a...
Re: Why is this nested for loop not printing 5 spaces on the top line?
If j starts at 5 and the loop condition is j>1 you'll get only 4 iterations (j = 5, 4, 3, 2)
The condition should be j>0 (or j>=1 if you prefer).
Struggling with generics
Hi all, this is my first post here. After not doing any much Java for 15 years (mostly C and C#) I decided to revisit my old Java projects. I'm using OpenJDK 11.0.12 because Microsoft was kind enough...
