Java getting the Enum name given the Enum Value

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(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()

Try, the following code..

    @Override
    public String toString() {
    return this.name();
    }
