How to make enums inside java class

package com.ekiras.demo;

public class User {
 
 public enum Gender{
  MALE,
  FEMALE
 }
 
 private String name;
 private String address;
 private String email;
 private String password;
 private Gender gender = Gender.MALE;
 
}

package com.ekiras.demo;

public class User {
 
 public enum Gender{
  MALE("male"),
  FEMALE("female");
  
  String value;
  Gender(String value){
   this.value=value;
  }
 }
 
 private String name;
 private String address;
 private String email;
 private String password;
 private Gender gender = Gender.MALE;
 
}
 

Points To Remember

• Enums are special java classes that are used to declare constants and methods.
• Enums have all the variables declared as public static final.
• Enums variables can be compared using == operator.
• End of a enum can be declared by a semi colon, but this is optional.
• There are two ways to use Enums 
• ORDINAL (saves the enum values in integer format starting from 0.)
• STRING (saves the enum value in String, takes the value of the field itself. )

Use Enums in Hibernate

package com.ekiras.enums;

public enum Level {

 LEVEL_ONE,
 LEVEL_TWO,
 LEVEL_THREE,
 LEVEL_FOUR,
 LEVEL_FIVE;
}

package com.ekiras.domain;

import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.EnumType;
import javax.persistence.Enumerated;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.Table;

import com.ekiras.enums.Level;

@Entity
@Table(name="question")
public class Question {
  
        @Id
        @Column(name="id")
        @GeneratedValue(strategy=GenerationType.AUTO)
        private Long id;

        @Column(name="question")
        private String question;

        @Column(name="level")
        @Enumerated(EnumType.ORDINAL)
        private Level status = Level.LEVEL_ONE;
  
        // GETTERS and SETTERS

}

        
 @Column(name="level")
 @Enumerated(EnumType.STRING)
 private Level status = Level.LEVEL_ONE;
