### Question:
ScriptExecutionBuilder { public Collection<String> build() { final List<String> commands = new ArrayList<String>(); commands.add(String.format("execute %s", getScriptName())); if (!arguments.isEmpty()) { final Iterator<Argument> argumentIterator = arguments.iterator(); commands.add(argumentIterator.next().getCommandLineValue()); while (argumentIterator.hasNext()) commands.add("," + argumentIterator.next().getCommandLineValue()); } if (!records.isEmpty()) { final Iterator<Entry<String, Record>> iterator = getRecordStructures().entrySet().iterator(); Entry<String, Record> entry = iterator.next(); commands.add(String.format("WITH REPLACE(\"%s\", \"%s\")", entry.getKey(), entry.getValue().getName().toUpperCase(Locale.getDefault()))); while (iterator.hasNext()) { entry = iterator.next(); commands.add(String.format(", REPLACE(\"%s\", \"%s\")", entry.getKey(), entry.getValue().getName().toUpperCase(Locale.getDefault()))); } } commands.add("go;" + getScriptName()); return commands; } private  ScriptExecutionBuilder(final String scriptName); static ScriptExecutionBuilder getBuilder(final String scriptName); void addWithReplace(final String recordName, final Record record); Collection<String> build(); String getScriptName(); ScriptExecutionBuilder withArguments(final List<Argument> arguments);  }### Answer:
