How to compare with a set of enum values-CodePudding

Hello I have an enum of months.

public enum Months{
JANUARY, FEBUARY, MARCH,
    APRIL, MAY, JUNE, JULY, AUGUST, SEPTEMBER, OCTOBER, NOVEMBER, DECEMBER;
}

In the service I have a method that should only work if the month is greater than MARCH i.e. APRIL, MAY, ..... How can I write the following line more eloquently:

public void monthCheck(Object object){
    if (object.month!= Months.JANUARY || object.month!= Months.FEBUARY || object.month != Months.MARCH){
        //do something here
    }
}

Your enum should have get/set methods like

public enum Months {
        JANUARY("january"), and so on;

        String months;
        Months(String months) {
            this.months = months;
        }

        public String getMonths() {
            return toggleStatus;
        }

}

Now when you do Months.JANUARY.getMonths() anywhere in your project this will return "january" value. If you write

JANUARY("1"), FEBRUARY("2")

Then it will return 1,2 and so on

You can use the ordinal() on the enum to achieve this.

public void monthCheck(Object object) {
    if(!(object instanceof Months)){
        return;
    }
    Months input = (Months) object;
    if( input.ordinal() > 2 ) {
        /* your logic here */
        System.out.println(input.ordinal());
    }
}

Try This Code Here:

public enum Months{
JANUARY, FEBUARY, MARCH,
    APRIL, MAY, JUNE, JULY, AUGUST, SEPTEMBER, OCTOBER, NOVEMBER, DECEMBER;


public void monthCheck(String str){
        if (!str.equals(Months.JANUARY) || 
                !str.equals(Months.FEBUARY) || !str.equals(Months.MARCH)){
        //do somwthing here
        }
    }
}
