How can I get the name of a Java Enum type given its value?

I have the following code which works for a particular Enum type, can I make it more generic?

public enum Category {



    APPLE("3"), 

    ORANGE("1"), 



    private final String identifier;



    private Category(String identifier) {

        this.identifier = identifier;

    }



    public String toString() {

        return identifier;

    }



    public static String getEnumNameForValue(Object value){

        Category values = Category.values();

        String enumValue = null;

        for(Category eachValue : values) {

            enumValue = eachValue.toString();



            if (enumValue.equalsIgnoreCase(value)) {

                return eachValue.name();

            }

        }

        return enumValue;

    }

}

You should replace your getEnumNameForValue by a call to the name() method.

Try below code

public enum SalaryHeadMasterEnum {



    BASIC_PAY("basic pay"),

    MEDICAL_ALLOWANCE("Medical Allowance");



    private String name;



    private SalaryHeadMasterEnum(String stringVal) {

        name=stringVal;

    }

    public String toString(){

        return name;

    }



    public static String getEnumByString(String code){

        for(SalaryHeadMasterEnum e : SalaryHeadMasterEnum.values()){

            if(code == e.name) return e.name();

        }

        return null;

    }

}

Now you can use below code to retrieve the Enum by Value

SalaryHeadMasterEnum.getEnumByString("Basic Pay")

Use Below code to get ENUM as String

SalaryHeadMasterEnum.BASIC_PAY.name()

Use below code to get string Value for enum

SalaryHeadMasterEnum.BASIC_PAY.toString()

Try, the following code..

    @Override

    public String toString() {

    return this.name();

    }

Here is the below code, it will return the Enum name from Enum value.

public enum Test {



    PLUS("Plus One"), MINUS("MinusTwo"), TIMES("MultiplyByFour"), DIVIDE(

            "DivideByZero");

    private String operationName;



    private Test(final String operationName) {

        setOperationName(operationName);

    }



    public String getOperationName() {

        return operationName;

    }



    public void setOperationName(final String operationName) {

        this.operationName = operationName;

    }



    public static Test getOperationName(final String operationName) {



        for (Test oprname : Test.values()) {

            if (operationName.equals(oprname.toString())) {

                return oprname;

            }

        }

        return null;

    }



    @Override

    public String toString() {

        return operationName;

    }

}



public class Main {

    public static void main(String args) {



        Test test = Test.getOperationName("Plus One");

        switch (test) {

        case PLUS:

            System.out.println("Plus.....");

            break;

        case MINUS:

            System.out.println("Minus.....");

            break;



        default:

            System.out.println("Nothing..");

            break;

        }

    }

}
