Java Development Kit Jdk 7u95

Sep 07, 2012  Java is one of the languages geared towards projects that have become more relevant in recent years, especially for its multiplatform capabilities. Java Development Kit (JDK) is a set of tools created by Sun whose purpose is to make the life of a Java developer easier.

What is the JDK? The JDK is a software package that contains a variety of tools and utilities that make it possible to develop, package, monitor and deploy applications that build for any standard Java platform, including Java Platform, Standard Edition (Java SE); Java Platform, Micro Edition (Java ME); and Java Platform, Enterprise Edition (). The Java platform In the past, it would have been correct to say that the JDK specifically targeted the program language Java. However, Java 7 introduced a special constructs that made it much easier for peripheral programming languages, such as Groovy, Clojure or Kotlin, to compile into Java bytecode and execute using the Java Runtime Environment (). As a result, the Java platform as it exists today includes not only Java, but a variety of other peripheral languages that use the JDK tools and execute on the Java runtime.

JDK components, tools and utilities The bin directory of the JDK provides a variety of features and tools that aid in the software development process. Some of the more popular JDK utilities include: • javac: This utility is used to compile Java source code into Java bytecode. • rmic: This utility creates skeletons and stubs for use in Remote Method Invocation (RMI). • jar: This compression utility aggregates a multitude of files into a single Java ARchive () file. The jar utility uses a standard compression algorithm used by all of the most common zip utilities. • javadoc: This utility can examine the names of classes and the methods contained within a class, as well as consume special annotations in order to create application programming interface () documentation for Java code.

• wsgen: This generates various artifacts required by Java API for XML Web Services (JAX-WS). • javap: This utility disassembles class files, generating information about the methods, properties and attributes of a given compiled component. The JDK also contains a number of tools for inspecting the runtime behavior of a JVM, including Java Mission Control (JMC), Java Flight Recorder (JFR) and VisualVM. Difference between the JDK and JVM Within the JDK bin directory, there is also a utility simply named java.

This utility will take any Java application containing a runnable main method and execute it as a software program. When a Java application's source code is compiled, it is compiled into bytecode.

Development

Bytecode is an intermediary between Java source code and low-level machine code. Jc higgins model 50. When the java utility is invoked, a JVM is created, which uses a just-in-time (JIT) compiler to convert bytecode into machine code. This on-the-fly conversion from Java bytecode to low-level computer instructions is the key to making a Java application cross-platform and hardware-agnostic.
