__FORCETOC__
[[Java]] comes with a range of tools for different purposes. We will introduce most of them below.

== Java Compiler == 

The Java [compiler] transforms programs written in the Java programming language in to Java bytecode, which can be executed in the [[Java#Java_Virtual_Machine|JVM]].

If you download the Java Development Kit from Oracle, the Java compiler is called javac.

=== javac === 

Examples on how to use java:

*If you want to compile a file called Hello.java you write:
*: <syntaxhighlight lang="bash">javac Hello.java</syntaxhighlight>
*If you want to compile a file called Hello.java and GoodBye.java you write:
*: <syntaxhighlight lang="bash">javac Hello.java GoodBye.java</syntaxhighlight>
*If you want to compile a file called Hello.java and GoodBye.java which are found in a packge called com.example you write:
*: <syntaxhighlight lang="bash">javac com/example/Hello.java com/example/GoodBye.java</syntaxhighlight>

== Java runtime environment ==


If you download the Java Development Kit or the Java Runtime Environment from Oracle, the [[Java|Java runtime environment]] is called java.

=== java ===

Examples on how to use java:

*If you want to run(or execute) a class file called Hello.java which is found in a packge called com.example you write:
*: <syntaxhighlight lang="bash">java com.example.Hello</syntaxhighlight>
*: This invokes the Java runtime environment and loads the class com.example.Hello, which in turn is started via its [[main method]].
