public class Enum_ordinalMethodExample1 {

enum Colours{

Red,Green,Brown,Yellow;
    }

public static void main(String[] args) {

Colours Red = Colours.Red;

Colours Green = Colours.Green;

Colours Brown = Colours.Brown;

Colours Yellow = Colours.Yellow;

System.out.println(" Red ordinal = "+Red.ordinal());

System.out.println(" Green Ordinal = "+Green.ordinal());

System.out.println(" Brown Ordinal = "+Brown.ordinal());

System.out.println(" Yellow Ordinal = "+Yellow.ordinal());
    }
}

Test it Now

Output:

Red ordinal = 0
 Green Ordinal = 1
 Brown Ordinal = 2
 Yellow Ordinal = 3

Example 2

public class Enum_ordinalMethodExample2 {

enum Position{

Reema("Panda"),Himanshu("Bhardwaj"),Geetanjali("Sharma");

      String lName;

Position(String s){

lName=s;
    }

    String showPosition(){

return lName;
    }
 }

public static void main(String[] args) {

for(Position pos : Position.values()){

int val = pos.ordinal()+1;

System.out.println("First name = "+pos+"\nLast name = "+pos.showPosition() +"\nPosition in class = "+val );

System.out.println();
        }
    }
}

Test it Now

Output:

First name = Reema
Last name = Panda
Position in class = 1

First name = Himanshu
Last name = Bhardwaj
Position in class = 2

First name = Geetanjali
Last name = Sharma
Position in class = 3

Example 3

public class Enum_ordinalMethodExample3 {

enum movie{

Don,DDlJ,Fan,Zero,VeerZara;
    }

public static void main(String[] args) {

movie Don,DDLJ,Fan,Zero;

        Zero= movie.Zero;

System.out.println("Movies of Shahrukh Khan:");

for(movie m:movie.values()){

// method will return the ordinals of the enum constants

System.out.println(m.ordinal()+" "+m);
        }

System.out.println("Q In which movie Shah rukh khan has played a dual role ?");

        String obj1="Don";

        String obj2 ="Zero";

        Boolean b1 =obj1.equals(obj2);

System.out.println("Ans. "+Zero.ordinal()+" "+ obj2 );

if(b1==true){

System.out.println("Your answer is correct.");
        }

else{

System.out.println("Sorry!You Failed.\n The Correct answer is Don.");
