Java is a high-level, general-purpose, memory-safe, object-oriented programming language.It is intended to let programmers write once, run anywhere (), [16] meaning that compiled Java code can run on all platforms that support Java without the need to recompile. [17]
Output report types: plain text, HTML, XML. All report types support drill-down, to a user-controlled detail depth. The HTML report supports source code linking. Output reports can highlight items with coverage levels below user-provided thresholds. Coverage data obtained in different instrumentation or test runs can be merged.
DrJava has the ability to interactively evaluate Java code from a console and to present output as well to the same console. [2] It has many other features that have been designed for advanced users as well. DrJava offers a JUnit test facility. [2] There have been 4,332,375 downloads as of May 1, 2021. [3]
The most common form of output from a Java compiler is Java class files containing cross-platform intermediate representation (IR), called Java bytecode. [2] The Java virtual machine (JVM) loads the class files and either interprets the bytecode or just-in-time compiles it to machine code and then possibly optimizes it using dynamic compilation.
Provides warnings if tagged parameters do not match code, parsed parameters included in XML output and Doxygen-style tagfile (-D flag in 8.7). Partial C preprocessor support with -p flag. Support for #if/#ifdef control over documentation inclusion using the -D and -U command-line flags. Imagix 4D: customizable through style sheets and CSS
Java bytecode is the instruction set of the Java virtual machine (JVM), the language to which Java and other JVM-compatible source code is compiled. [1] Each instruction is represented by a single byte , hence the name bytecode , making it a compact form of data .
The Java platform is a suite of programs that facilitate developing and running programs written in the Java programming language. A Java platform includes an execution engine (called a virtual machine), a compiler and a set of libraries; there may also be additional servers and alternative libraries that depend on the requirements.
