Line 39:

There are also a few instructions for a number of more specialized tasks such as exception throwing, synchronization, etc.

Many instructions have [[Opcode prefix|prefixes]] and/or suffixes referring to the types of operands they operate on.<ref name="jvm"/>{{rp|2.11.1}} These are as follows:

{| class="wikitable"

Line 77:

continue outer;

}

System.out.println (i);

Line 123:

Others have developed compilers, for different programming languages, to target the Java virtual machine, such as:

*[[ColdFusion Markup Language|ColdFusion]]

*[[JRuby]] and [[Jython]], two [[scripting language]]s based on [[Ruby (programming language)|Ruby]] and [[Python (programming language)|Python]]

*[[Groovy (programming language)|Apache Groovy]], optionally typed and dynamic general-purpose language, with static-typing and static compilation capabilities

Line 145:

The [[Java virtual machine]] provides some support for [[Type system#Dynamic typing|dynamically typed languages]]. Most of the extant JVM instruction set is [[Type system#Static typing|statically typed]] - in the sense that method calls have their signatures type-checked at [[compile time]], without a mechanism to defer this decision to [[Run time (program lifecycle phase)|run time]], or to choose the method dispatch by an alternative approach.<ref>{{cite web
