Calling methods java-CodePudding

I have a enum and every enum must have specific fields, such as price, which will not be modified, and I want to create a class to get this fields, what can I do in this situation? How can I call the class using the enums or what can I do?

You can try this :

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(e.name.equals(code)) 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()

An enum is a special type of class that represents a group of fianl values. if you want to get the field then you make instance like

 Price myVar = Price.Low;
 System.out.println(myVar);
