如何在java中使用enum键值

我想在Java11中创建一个带有键值的枚举类 我创建了这样一个枚举

public enum status{

    ACTIVE("Active", 1), IN_ACTIVE("In Active", 2);

    private final String key;
    private final Integer value;

    Status(String key, Integer value) {
        this.key = key;
        this.value = value;
    }

    public String getKey() {
        return key;
    }
    public Integer getValue() {
        return value;
    }
}

[
"ACTIVE",
"INACTIVE"
]

[
{
"Key": "Inactive", 
"value":"2"
},
{
"Key": "Active",
 "value":"1"
}
]

问题是当我执行Saison Saison.getvalues（）时 我是这样的

public enum status{

    ACTIVE("Active", 1), IN_ACTIVE("In Active", 2);

    private final String key;
    private final Integer value;

    Status(String key, Integer value) {
        this.key = key;
        this.value = value;
    }

    public String getKey() {
        return key;
    }
    public Integer getValue() {
        return value;
    }
}

[
"ACTIVE",
"INACTIVE"
]

[
{
"Key": "Inactive", 
"value":"2"
},
{
"Key": "Active",
 "value":"1"
}
]

但我想这样

public enum status{

    ACTIVE("Active", 1), IN_ACTIVE("In Active", 2);

    private final String key;
    private final Integer value;

    Status(String key, Integer value) {
        this.key = key;
        this.value = value;
    }

    public String getKey() {
        return key;
    }
    public Integer getValue() {
        return value;
    }
}

[
"ACTIVE",
"INACTIVE"
]

[
{
"Key": "Inactive", 
"value":"2"
},
{
"Key": "Active",
 "value":"1"
}
]

如何调用我的enum tio以获得这样的结果

没有什么可以阻止您返回包含

键、值

对的映射条目

public enum status{

    ACTIVE("Active", 1), IN_ACTIVE("In Active", 2);

    private final String key;
    private final Integer value;

    Status(String key, Integer value) {
        this.key = key;
        this.value = value;
    }

    public String getKey() {
        return key;
    }
    public Integer getValue() {
        return value;
    }
}

[
"ACTIVE",
"INACTIVE"
]

[
{
"Key": "Inactive", 
"value":"2"
},
{
"Key": "Active",
 "value":"1"
}
]

 enum Status {

    ACTIVE("Active", 1), IN_ACTIVE("In Active", 2);

    private final String key;
    private final int value;

    Status(String key, int value) {
        this.key = key;
        this.value = value;
    }

    public String getKey() {
        return key;
    }
    public int getValue() {
        return value;
    }
    public Entry<String,Integer> getBoth() {
        return new AbstractMap.SimpleEntry<>(key, value);
    }   
}

Entry<String,Integer> e = Status.ACTIVE.getBoth();
System.out.println("Key: = " + e.getKey());
System.out.println("Value: = " + e.getValue());

印刷品

Key: = Active
Value: = 1
Active=1

"key": Active",
"value": "1"

    

您还可以覆盖枚举的toString并执行类似的操作

public String toString() {
    return String.format("\"key\": \"%s\",%n\"value\": \"%s\"",
            getKey(), getValue());
}

System.out.println(Status.ACTIVE);

印刷品

Key: = Active
Value: = 1
Active=1

"key": Active",
"value": "1"

你的意思是当试图编码为json时？`saison.getvalues（）`好吧，在你的问题中没有

saison

。此外，类名应该是PascalCase，因此

Status

或

Saison

，而不是

Status

或

Saison

。另外，输出应该是JSON吗？如果是这样的话，你可能想寻找专门的工具来解决这个问题。你在做什么？Java枚举没有getValues（）方法。。。什么是赛森？非常感谢你的帮助，现在已经开始工作了。
