Whereas in traditional languages one would have to include code to test the success or failure based on Boolean logic and then branch based on the outcome, such tests and branches are inherent to Icon code and do not have to be explicitly written. [21] For instance, consider this bit of code written in the Java programming language.
compare two doubles, -1 on NaN dconst_0 0e 0000 1110 → 0.0 push the constant 0.0 (a double) onto the stack dconst_1 0f 0000 1111 → 1.0 push the constant 1.0 (a double) onto the stack ddiv 6f 0110 1111 value1, value2 → result divide two doubles dload 18 0001 1000 1: index → value load a double value from a local variable #index: dload_0 26
The Byte Code Engineering Library (BCEL) is a project sponsored by the Apache Foundation previously under their Jakarta charter to provide a simple API for decomposing, modifying, and recomposing binary Java classes (I.e. bytecode). The project was conceived and developed by Markus Dahm prior to officially being donated to the Apache Jakarta ...
Prior to Flutter 2.0, developers could only target Android, iOS and the web. Flutter 2.0 released support for macOS, Linux, and Windows as a beta feature. [67] Flutter 2.10 released with production support for Windows [68] and Flutter 3 released production support for all desktop platforms. [69] It provides a framework, widgets, and tools.
Flutter is an open-source UI software development kit created by Google. It can be used to develop cross platform applications from a single codebase for the web, [3] Fuchsia, Android, iOS, Linux, macOS, and Windows. [4] First described in 2015, [5] [6] Flutter was released in May 2017.
Java compilers do not enforce these rules, but failing to follow them may result in confusion and erroneous code. For example, widget.expand() and Widget.expand() imply significantly different behaviours: widget.expand() implies an invocation to method expand() in an instance named widget , whereas Widget.expand() implies an invocation to ...
The first Java GUI toolkit was the Abstract Window Toolkit (AWT), introduced with Java Development Kit (JDK) 1.0 as one component of Sun Microsystems' Java platform. The original AWT was a simple Java wrapper library around native (operating system-supplied) widgets such as menus, windows, and buttons.
The phrase grammar of most programming languages can be specified using a Type-2 grammar, i.e., they are context-free grammars, [8] though the overall syntax is context-sensitive (due to variable declarations and nested scopes), hence Type-1. However, there are exceptions, and for some languages the phrase grammar is Type-0 (Turing-complete).
