Pass setter value to constructor

Question

I need to pass a setter value (set by jbpm call) to a contructor in Java. Is it possible? JBPM calls a constructor with no arguments. So my only way out is to set that value and pass it as a parameter to contructor? Thanks.

You need to look at the concept of Parametrized constructor. You can create a object using the parametrized constructor and call the default one from it, like

class MainClass {
    String name;
    public MainClass(){
        System.out.println("In default constructor");
    }

    public MainClass(String name) {
        this();
        System.out.println("In constructor with a String");
    }
}
