How to unbox values returned by javascript (nashorn) in Java object? -

i have following program, executes javascript in java (nashorn) . javascript code returning object.

public object execute(){         scriptenginemanager sem = new scriptenginemanager();         scriptengine e = sem.getenginebyname("nashorn");           invocable invocable = (invocable)e;         scriptenginefactory f = e.getfactory();         object result;         try {             string statement = "function fetch(value, count) { count++ ; return {'value': value,'count' : count} }; } ; ";             compiledscript cs = ((compilable)e).compile(statement);             cs.eval();             result = invocable.invokefunction("fetch", 10,2);          }            catch (exception se ) {             string version = system.getproperty("java.version");             system.out.println(version);             result = "script exception ";         } 

how access object values in result object in java? initially, tried using result.tostring() results. seems return [object object]

is there way, return results result object such values equivalent result.value , , result.count (similar javascript) .

you don't return jsobject javascript function. valid be

{   value: value,   count : count } 

so use java code.

package de.lhorn.so;  import javax.script.compilable; import javax.script.compiledscript; import javax.script.invocable; import javax.script.scriptengine; import javax.script.scriptenginemanager; import javax.script.scriptexception; import jdk.nashorn.api.scripting.jsobject;  public class soplayground {      public static void main(string[] args) throws exception {         soplayground sop = new soplayground();         jsobject jso = sop.execute();         system.out.println("value=" + jso.getmember("value"));         system.out.println("count=" + jso.getmember("count"));     }      public jsobject execute() throws scriptexception, nosuchmethodexception {         final scriptengine engine = new scriptenginemanager().getenginebyname("nashorn");         final compilable compilable = (compilable) engine;         final invocable invocable = (invocable) engine;          final string statement =           "function fetch(value, count) { count++ ; return {value: value, count : count} };";         final compiledscript compiled = compilable.compile(statement);          compiled.eval();          return (jsobject) invocable.invokefunction("fetch", 10, 2);     } } 

output:

value=10 count=3.0
