Tribuo is a machine learning library in Java that provides multi-class classification, regression, clustering, anomaly detection and multi-label classification.

Java may have been designed as a completely object oriented language, but when Java SE 8 was released in 2014, it added Lambda expressions (aka closures), which added some functional programming elements. Not every problem is best served by OOP, and by adding Lambdas, Java became more flexible.

To help you get started quickly, we created a special Installer of Visual Studio Code for Java developers. Download Visual Studio Code Java Pack Installer Note: The installer is currently only available for Windows. For other OS, please install those components (JDK, VS Code and Java extensions) individually. We're working on the macOS version, please stay tuned. The package can be used as a clean install or an update for an existing development environment to add Java or Visual Studio Code. Once downloaded and opened, it automatically detects if you have the fundamental components in your local development environment, including the JDK, Visual Studio Code, and essential Java extensions.

CoffeeScript is to Ruby as TypeScript is to Java/C#/C++.

Headers in a manifest Header Definition Name The name of the specification. Specification-Title The title of the specification. Specification-Version The version of the specification. Specification-Vendor The vendor of the specification. Implementation-Title The title of the implementation. Implementation-Version The build number of the implementation. Implementation-Vendor The vendor of the implementation.

To load classes in JAR files within a JAR file into the class path, you must write custom code to load those classes. For example, if MyJar.jar contains another JAR file called MyUtils.jar, you cannot use the Class-Path header in MyJar.jar's manifest to load classes in MyUtils.jar into the class path.

The Class-Path header points to classes or JAR files on the local network,

To modify the manifest, you must first prepare a text file containing the information you wish to add to the manifest. You then use the Jar tool's m option to add the information in your file to the manifest.

Warning: The text file from which you are creating the manifest must end with a new line or carriage return. The last line will not be parsed properly if it does not end with a new line or carriage return.

As an example, suppose you wanted to put audio files and gif images used by the TicTacToe demo into a JAR file, and that you wanted all the files to be on the top level, with no directory hierarchy. You could accomplish that by issuing this command from the parent directory of the images and audio directories: jar cf ImageAudio.jar -C images . -C audio .

Full disclosure: I’m a co-maintainer of clj-time and I’m pretty vocal about encouraging people not to use clj-time when starting a new project: use Java Time instead. Conversion from an existing, clj-time-heavy project is another matter tho’, unfortunately.

in general, clojure doesn't have java interop, it has jvm interop so in places where the java language doesn't map 1:1 to the jvm, clojure gives something that matches the raw jvm, not something that matches the java language

Perhaps part of the confusion - and you say this in a different way in your little memo - is that the C/C++ folks see OO as a liberation from a world that has nothing resembling a first-class functions, while Lisp folks see OO as a prison since it limits their use of functions/objects to the style of (9.). In that case, the only way OO can be defended is in the same manner as any other game or discipline -- by arguing that by giving something up (e.g. the freedom to throw eggs at your neighbor's house) you gain something that you want (assurance that your neighbor won't put you in jail).

Sum-of-product-of-function pattern - objects are (in effect) restricted to be functions that take as first argument a distinguished method key argument that is drawn from a finite set of simple names.

All you can do is send a message (AYCDISAM) = Actors model - there is no direct manipulation of objects, only communication with (or invocation of) them. The presence of fields in Java violates this.

Parametric polymorphism - functions and data structures that parameterize over arbitrary values (e.g. list of anything). ML and Lisp both have this. Java doesn't quite because of its non-Object types.

Addition Operation Using Bitwise Operators In Java

but the true technology of Java is not in the language, but the virtual machine itself. The JVM as it stands today, is a fast, abstract machine that you can plug any languages into, and is able to operate at speeds comparable to natively compiled binaries.

Optimum buffer size is related to a number of things: file system block size, CPU cache size and cache latency. Most file systems are configured to use block sizes of 4096 or 8192. In theory, if you configure your buffer size so you are reading a few bytes more than the disk block, the operations with the file system can be extremely inefficient (i.e. if you configured your buffer to read 4100 bytes at a time, each read would require 2 block reads by the file system). If the blocks are already in cache, then you wind up paying the price of RAM -> L3/L2 cache latency. If you are unlucky and the blocks are not in cache yet, the you pay the price of the disk->RAM latency as well. This is why you see most buffers sized as a power of 2, and generally larger than (or equal to) the disk block size. This means that one of your stream reads could result in multiple disk block reads - but those reads will always use a full block - no wasted reads. Now, this is offset quite a bit in a typical streaming scenario because the block that is read from disk is going to still be in memory when you hit the next read (we are doing sequential reads here, after all) - so you wind up paying the RAM -> L3/L2 cache latency price on the next read, but not the disk->RAM latency. In terms of order of magnitude, disk->RAM latency is so slow that it pretty much swamps any other latency you might be dealing with. So, I suspect that if you ran a test with different cache sizes (haven't done this myself), you will probably find a big impact of cache size up to the size of the file system block. Above that, I suspect that things would level out pretty quickly. There are a ton of conditions and exceptions here - the complexities of the system are actually quite staggering (just getting a handle on L3 -> L2 cache transfers is mind bogglingly complex, and it changes with every CPU type). This leads to the 'real world' answer: If your app is like 99% out there, set the cache size to 8192 and move on (even better, choose encapsulation over performance and use BufferedInputStream to hide the details). If you are in the 1% of apps that are highly dependent on disk throughput, craft your implementation so you can swap out different disk interaction strategies, and provide the knobs and dials to allow your users to test and optimize (or come up with some self optimizing system).

Think Java: How To Think Like a Computer Scientist

Java Programming Language was developed by James Gosling, Chris Warth, Patrick Naughton, Mike Sheridan and Ed Frank at Sun Microsystems, Inc in the year 1991. At first Java Programming Language was named as Oak, later that it was renamed to Java in the year 1995. Java Programming is a platform independent language. The Internet (World Wide Web) made Java programming more valuable. Since, Internet is connected to different types of systems which having different CPU's & environments, it must have the programs to run on any OS, CPU and Platform. Since, Java programming obtain platform independence and can able to run on any platform like Unix, Intel, Mac etc., it was widely used. Java language also protects two other major issues of Internet, they are security & portability.
