### Question:
BSHMethod { protected Interpreter initInterpreter(Map arguments) throws EvalError, IOException { Interpreter i = new Interpreter(); Map.Entry entry; for (Object o : arguments.entrySet()) { entry = (Map.Entry) o; i.set((String) entry.getKey(), entry.getValue()); } if (source) { i.source(bshData); } else { i.eval(bshData); } return i; } BSHMethod(String bshData, boolean source); static BSHMethod createBshMethod(Element e); Object execute(Map arguments, String resultName); Map execute(Map arguments, Collection returnNames); String toString();  }### Answer:
