Basic Java Tools

Java development Kit (JDK) provides tools to compile and build applications. These tools are the foundation of the JDK. JDK stores these tools in below directories.

In previous article, we installed JDK in C:\Program Files\Java\jdk1.6.0_39\. Go to C:\Program Files\Java\jdk1.6.0_39\bin directory.

 

 

Most of the time we will be using below tools to build/deploy the applications.

javac

The compiler for the Java programming language. It is the Java compiler that converts the Java source code into Java bytecode.

java

The launcher for Java applications. The Java interpreter that executes Java application bytecodes from the class files. In this release, a single launcher is used both for development and deployment.

Jar

Create and manage Java Archive (JAR) files. Jar files are compressed files bundling multiple Java classes and resources together.

javadoc

The Java documentation utility that creates HTML documentation based on Java source code and the comments it contains.

 

Below Diagram shows usage of Javac and Java command.
