Question

我有一类不同部分的问题 - 根据其他答案向用户显示某些部分。第1节总是得到回答。第2节＆amp;只有在某些情况下才会回答3。

我应该如何最好＆＃34; group＆＃34;这些问题，以便我可以轻松检查给定组中的真实答案的总数（包含true / false）并检查这些部分是否每个问题回答

问题中的数据是从Spring项目中的Web UI返回的。我认为可能的值为true，false或null。

@Entity
public class LicenseApplication {
    // Section 1
    private boolean question1;
    private boolean question2;

    //Section 2
    private boolean question3;
    private boolean question4;
}

Answer 1

你可以做类似以下的事情

class Section
{
    public List<Question> questions;
    //...
}

class Question
{
    public boolean isCorrect;
    //...
}

public boolean entireSectionCorrect(Section section)
{
    for (int i=0; i<section.questions.size(); i++) {
        if(!section.questions[i].isCorrect)
            return false;
    }

    return true;
}

@AlanCPSC提出了很好的建议，因为纠正了一些事情

class Section
{
    private List<Question> questions;
    public int getCount()
    {     
         int count=0;
        for(Question quest : questions)
        {
             boolean answer    = quest.getAnswer().get(quest.getQuestion());
             boolean answered  = quest.getAnswered().get(quest.getQuestion());
            if(answer == answered)
            {
              count++;
            }
        }
         return count;
    }
    ...
}

class Question
{
    private String question;
    private Map<String, Boolean> answer; // correct answer
    private Map<String, Boolean> answered; // answered by candidate
    ...
}

Answer 3

我对OP的混乱以及其他答案的过分感到有些失望，所以这是我的看法......

免责声明：我已经离开java一段时间了，而且我已经通过记忆对此进行了编码...原谅任何错误（但请指出它们以便我解决它们）。

var displayMatches = function(){
    let val = this.value;
    console.log(val);
    var matchArray = findMatches(val, cities);
    var html = matchArray.map(function(place){
        console.log(this, place, "test");
        var regex = new RegExp(val, 'gi');
        var cityName = place.city.replace(regex, "<span class='hl'>" + val + "</span>");
        var stateName = place.state.replace(regex, "<span class='hl'>" + val + "</span>");
            return `
          <li>
            <span class="name">${cityName}, ${stateName}</span>
            <span class="population">${place.population}</span>
          </li>
            `;
    }).join("");
    suggestions.innerHTML = html;
}
