java - 从 hashmap 打印一个值到屏幕 - 一次打印多个值？

Question

我有一个带有整数键和附加字符串的 HashMap 。 用户可以选择多个值，我希望所有值都显示在屏幕上。请看下面的代码:

  Integer[] twistedThinking = {allOrNothing, blamingOthers, catastrophizing, emotionalReasoning, fortuneTelling,
    labelling, magnifying, mindReading, minimising, overGeneralisation, selfBlaming, shouldStatements};

    for(Integer key: twistedThinking){
        key=twistedThought;
    }

    Map<Integer, String> twistedThoughtsMap = new HashMap<>();
    twistedThoughtsMap.put(allOrNothing, "All or Nothing Thinking");
    twistedThoughtsMap.put(blamingOthers, "Blaming Others");
    twistedThoughtsMap.put(catastrophizing, "Catastrophizing");
    twistedThoughtsMap.put(emotionalReasoning, "Emotional Reasoning");
    twistedThoughtsMap.put(fortuneTelling, "Fortune Telling");
    twistedThoughtsMap.put(labelling, "Labelling");
    twistedThoughtsMap.put(magnifying, "Magnifying the Negative");
    twistedThoughtsMap.put(mindReading, "Mind Reading");
    twistedThoughtsMap.put(minimising, "Minimising the Positive");
    twistedThoughtsMap.put(overGeneralisation, "Over Generalisation");
    twistedThoughtsMap.put(selfBlaming, "Self-Blaming");
    twistedThoughtsMap.put(shouldStatements, "Should Statements");

    // Enhanced for loop searches the HashMap for any keys and sets the appropriate background.
    for (Integer key : twistedThinking) {
        if (twistedThought == key) {
            DistortionLogDetails.setText(twistedThoughtsMap.get(key));

        }

    }

目前这段代码只会将列表中的最后一个值打印到屏幕上。因此，如果用户最后选择的值是“SelfBlaming”，则只会打印那个值，而忽略所有其他先前的值。有解决这个问题的简单方法吗？

编辑:

1) 只是为了澄清用户的信息来自 mysql 数据库。

2) 变量 allOrNothing、blamingOthers 等的数值为 1、2 等，直到 12。

所以从 mySQL 服务器返回的数据是这样的:

     "allOrNothing": null,
     "blamingOthers": null,
     "catastrophizing": null,
     "emotionalReasoning": null,
     "fortuneTelling": "5",
     "labelling": null,
     "magnifyingTheNegative": "7",
     "mindReading": "8",
     "minimisingThePositive": "9",
     "overGeneralisation": null,
     "selfBlaming": null,
     "shouldStatements": null

在此示例中，用户有四个选择，因此，算命、放大负数、读心术和最小化正数都应显示在 SetText 中。

Answer 1

您可以考虑使用 Java“枚举”:

示例代码:

package com.example.cbt;

public class CBT {

    public enum TwistedThinking {
        allOrNothing, blamingOthers, catastrophizing, emotionalReasoning, fortuneTelling,
        labelling, magnifying, mindReading, minimising, overGeneralisation, selfBlaming,
        shouldStatements
    };


    public static void main(String[] args) {
        for (TwistedThinking thought : TwistedThinking.values()) {
            System.out.println("Thought(" + thought.ordinal() + ")=" + thought.name());
        }
    }

}

示例输出:

Thought(0)=allOrNothing
Thought(1)=blamingOthers
Thought(2)=catastrophizing
Thought(3)=emotionalReasoning
Thought(4)=fortuneTelling
Thought(5)=labelling
Thought(6)=magnifying
Thought(7)=mindReading
Thought(8)=minimising
Thought(9)=overGeneralisation
Thought(10)=selfBlaming
Thought(11)=shouldStatements
