java - passing a double value by reference

Question

how can I pass a double value by reference in java?

example:

Double a = 3.0;
Double b = a;
System.out.println(\"a: \"+a+\" b: \"+b);
a = 5.0;
System.         


        

Answer 1

You can try MutableDouble from commons-lang.

But not that this has nothing to do with pass-by-reference - you are not passing anything.
