======Command jset======

====Name====
**jset** Sets a variable as a result of creating a java object or calling a java method.

====Synopsis====
jset [options] [args ...]

====Description====
Jset creates a new Java Object or calls a static or instance method on that object or a supplied object.
The result is assigned to the named variable.

See [[FunctionJnew jnew]] and [[JavaObjects Java Objects]] for a function equivalent.


===Options===
||-v,-variable name||Assigns the result to the named variable in the current scope||
||-c,-classname classname||Creates a new instance of a class given its fully qualified classname and calls the a constructor||
||-m,-method method||Calls an instance method on the object specified with -object or a static method if no -object ||
||-o,-object object||Uses the specified object for a method call (-method)||
||-f,-field field||Gets the value of a field of a static class or instance||

-variable is required and the name is the name of an existing or to be created variable in the current scope.
If -classname is passed then the classname is used to either create a new variable or if -m is specified calling a static method on classname.
If -method is supplied then an instance method is called (requires -object)
If -object is supplied then -method is required and the specified method is invoked on the object.


If any additional arguments are specified they are used as the argument list for the constructor or method call,
using the same boxing and conversions in [[JavaObjects Java Objects]].



In all cases the result value (new object or return from method call) is assigned to the specified variable.
