The Java Development Kit maintains a CA keystore file named cacerts in folder jre/lib/security. JDKs provide a tool named keytool [ 1 ] to manipulate the keystore. keytool has no functionality to extract the private key out of the keystore, but this is possible with third-party tools like jksExportKey, CERTivity, [ 2 ] Portecle [ 3 ] and ...
The virtual machine will only load the class files required for executing the program. [2] The Java run time system does not need to know about files and file systems as this is delegated to the class loader. A software library is a collection of related object code. In the Java language, libraries are typically packaged in JAR files. Libraries ...
Early versions of Java Web Start came with an application manager where, e.g., Sun's demo applications could be launched. The developer prepares a special XML file with JNLP extension. This file describes the application requirements, code location, parameters and additional permissions (if any).

A JVM language is any language with functionality that can be expressed in terms of a valid class file which can be hosted by the Java Virtual Machine. A class file contains Java Virtual Machine instructions (Java byte code) and a symbol table, as well as other ancillary information. The class file format is the hardware- and operating system ...
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.
idlj – the IDL-to-Java compiler. This utility generates Java bindings from a given Java IDL file. jabswitch – the Java Access Bridge. Exposes assistive technologies on Microsoft Windows systems. java – the loader for Java applications. This tool is an interpreter and can interpret the class files generated by the javac compiler. Now a ...
Java bytecode is used at runtime either interpreted by a JVM or compiled to machine code via just-in-time (JIT) compilation and run as a native application. As Java bytecode is designed for a cross-platform compatibility and security, a Java bytecode application tends to run consistently across various hardware and software configurations. [3]
