Hi friends

guide me

to sorting java list contains multiple list objects
If you have a list of objects that you want to sort then the objects have to define
a (mathematically speaking) PTO (Partial Total Ordering). It implies that you
have to be able to determine if O1 < O2 or O1 == O2. The relation O1 > O2
follows from the other two relations. Java solves this by demanding the class to
implement the Comparable interface; or alternatively you have to create
an external Comparator that implements the relations.

Read the API documentation for the interfaces mentioned above and also study
the Collections.sor t() method.

kind regards,

Jos

After many years of using LISP, I'm taking a class in Java and finding the two roughly comparable in some ways and very different in other ways. Each has a decent size library of useful utilities as a standard portable part of the core language, the LISP package, and the java.lang package, respectively. Both have big integers, although only LISP has rationals as far as I can tell. Because CL supports keyword arguments, it has a wider range...

Java programmers seem to always be whining about how confusing and overly complex C++ appears to them. I would like to introduce an explanation for this. Is it possible that Java programmers simply aren't smart enough to understand C++? This is not merely a whimsical hypothesis. Given my experience with Java programmers --- the code they write and the conversations they have --- Occam's Razor points to this explanation. For example,...

Hello, I want to implement a generic list which will be used to display 7 columns in a GridView. One should be able to sort, filter and page each of the 7 columns. Ideally the filter should be implemented simultaneously for multiple columns - but the data need only be sorted by a single column at a time. Sorting should be both ascending and descending. I'm currently using a DataView but it's far too slow, because there are a large...

Hello folks, I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".

Overview: 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,...

Let's talk about the concept of autonomous AI software engineers and no-code agents. These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention. Imagine an AI that can take a project description, break it down, write the code, debug it, and then launch it, all on its own.... Now, this would greatly impact the work of software developers. The idea...
