DetailsDetails

  • To use MakeJavaObject, you first need to load J/Link using Needs["JLink`"].
  • MakeJavaObject is shorthand for calling JavaNew.
  • It is typically used when you need to call a Java method that is typed to take Object, and you want to pass it a numeric, string, or array value. You use MakeJavaObject to manually convert such arguments into Java objects before passing them to the method.
  • expr must be an integer or real number; a String; a Boolean; or a list or matrix of numbers, strings, or Booleans.
  • For an integer expr, the created Java object is of type java.lang.Integer.
  • For a real, the created Java object is of type java.lang.Double.
  • For a String, the created Java object is of type java.lang.String.
  • For a Boolean, the created Java object is of type java.lang.Boolean.
  • For a list or matrix of numbers, strings, or Booleans, the created object is a Java array of the corresponding primitive type. For example, MakeJavaObject[{1, 2, 3}] would create an with these values.
