To answer this question, we need to understand the difference between the methods getParameterValue() and getParameterValues() in the ServletRequest interface.
Option A) getParameterValue() - This option is incorrect because the getParameterValue() method returns a single value associated with a parameter. It does not return multiple values.
Option B) getParameters() - This option is incorrect because the getParameters() method returns a Map object containing all parameter names and their corresponding values. It does not specifically return multiple values associated with a single parameter.
Option C) getParamValues() - This option is incorrect because the getParamValues() method does not exist in the ServletRequest interface.
Option D) getParameterValues() - This option is correct because the getParameterValues() method returns an array of String objects containing all values associated with a parameter. If multiple values are associated with a parameter, this method allows you to retrieve all of them.
Therefore, the correct answer is option D. The getParameterValues() method returns more than one value associated with a parameter.
