Java is a high-level, class-based, object-oriented programming language that is designed to have as few implementation dependencies as possible.
The traditional Hello world program can be written in Java as: [57] public class HelloWorldApp { public static void main ( String [] args ) { System . out . println ( "Hello World!" ); // Prints the string to the console. } } All source files must be named after the public class they contain, appending the suffix .java , for example, HelloWorldApp.java . It must first be compiled into bytecode, using a Java compiler , producing a file with the .class suffix ( HelloWorldApp.class , in this case). Only then can it be executed or launched. The Java source file may only contain one public class, but it can contain multiple classes with a non-public access modifier and any number of public inner classes . When the source file contains multiple classes, it is necessary to make one class (introduced by the class keyword) public (preceded by the public keyword) and name the source file...
I’ll say it again: Python is a bad programming language, and the only reason it’s so popular today is because Google pushed it so hard in the first decade of the 2000s. The creator of Python, Guido van Rossum, actually worked at Google from 2005 to 2012. Go and Dart weren’t around back then (or at least they weren’t well known) and with C# gaining in popularity (stealing would-be Java developers) Google probably felt they needed a language of their own. They probably would have wanted to embrace Java, as they were already using it with Android, but they must have been paranoid about getting into bed with it because they were already running into legal issues with Oracle. So for whatever reason, they adopted Python. I imagine in an alternate universe they could have chosen, say, Lua, and maybe in that universe Lua would have become the dominant language today. Of course Lua is kinda weird, so it’s probably better they didn’t choose that one after all. But let’s talk about why Pytho...
Linux was originally developed for personal computers based on the Intel x86 architecture, but has since been ported to more platforms than any other operating system.Because of the dominance of the Linux-based Android on smartphones, Linux also has the largest installed base of all general-purpose operating systems.Although it is used by only around 2.3 percent of desktop computers,[26][27] the Chromebook, which runs the Linux kernel-based Chrome OS, dominates the US K–12 education market and represents nearly 20 percent of sub-$300 notebook sales in the US. Linux is the leading operating system on servers (over 96.4% of the top 1 million web servers' operating systems are Linux), leads other big iron systems such as mainframe computers, and is the only OS used on TOP500 supercomputers (since November 2017, having gradually eliminated all competitors). Linux also runs on embedded systems, i.e. devices whose operating system is typically built into the firmware and is highly tailo...
