Now a single launcher is used for both development and deployment. This tool is an interpreter and can interpret the class files generated by the javac compiler.
appletviewer – this tool can be used to run and debug Java applets without a web browser.The JDK has as its primary components a collection of programming tools, including: Oracle's primary implementation of the JVMS is known as the HotSpot (virtual machine). Previous versions have supported the Oracle Solaris operating system and SPARC architecture. Oracle release binaries for the x86-64 architecture for Windows, macOS, and Linux based operating systems, and for the aarch64 architecture for macOS and Linux. Oracle have released the current version of the software under the Oracle No-Fee Terms and Conditions ( NFTC) license. Examples of included software are the virtual machine, a compiler, performance monitoring tools, a debugger, and other utilities that Oracle considers useful for a Java programmer. It provides software for working with Java applications. It is derivative of the community driven OpenJDK which Oracle stewards. It implements the Java Language Specification ( JLS) and the Java Virtual Machine Specification ( JVMS) and provides the Standard Edition ( SE) of the Java Application Programming Interface ( API). The Java Development Kit ( JDK) is a distribution of Java Technology by Oracle Corporation.
The table below lists packages that are comprised in each profile.Oracle No-Fee Terms and Conditions (NFTC) with third party components Each profile specifies a particular set of Java API packages and contains all of the APIs in profiles smaller than itself: compact1 is a subset of compact2, which is a subset of compact3, which in its turn is a subset of the full JRE. Three profiles that have been defined so far are named compact1, compact2, and compact3.
