Long j=(Long)conn.k(“v”);

check if exists with x in key`.
e.g.

Long j=(Long)c.k(“{$[x in key.;value x;0N]}v”);

here return 0N if it doesn’t exist in root namespace

ahhh thanks, I just tested this in the console and it worked!

btw, in:
(Long)c.k(“…”);

did you mean “conn” instead of c? thats what I have my c object named as.

cheers

yes, sorry.

I set j as an instance of the “Object” class so it works on variables that are other data types, not just ints.

It prints out single characters, but i set a:“test”, it returns a memory address, do you know how I fix this?

see method t in c.java

public static int t(Object x)

returns the k datatype for that object
