The INVOKE and NEW commands

INVOKE

NEW

NEW is used to create (construct) a Java object.

nM> new java.lang.Double("10.12345678901234567") D
nM> res d.getClass()
  O: D.GETCLASS()    = class java.lang.Double

INVOKE is used to call complex methods in a Java object.

nM> new java.lang.String("a string with more") str
nM> invoke ,,str.regionMatches(0,"a string",0,8)
Invoke: ANSWER = true

INVOKE and NEW can be very powerful tools for evaluating and understanding how to use Java classes.

NeXtMidas automatically converts the arguments for `INVOKE` and `NEW` from strings into objects. This creates a number of limitations: If multiple methods have the same name the "wrong" one may be called (e.g. `setFoo(int)` and `setFoo(String)` when given `2`) It is not possible to use a `null` since it is treated as the string `"null"`. It is difficult to call a method that takes in an object array.
