Description:

This example gives you how to create custom constructor for enum. The constructor should be either private or default scope, should not be protected or public. All elements defined in the enum must call constructor.


Code:
package com.java2novice.enums;

public class MyEnumCustomConstructor {

	enum Department{
		
		ACCOUNT(12),HR(24),FINANCE(100),SECURITY(108);
		
		private int deptId;
		
		Department(int id){
			deptId = id;
		}
		
		public int getDeptId(){
			return deptId;
		}
	}
	
	public static void main(String a[]){
		System.out.println("Accounts dept id:"+Department.ACCOUNT.getDeptId());
		System.out.println("HR dept id:"+Department.HR.getDeptId());
		System.out.println("Security dept id:"+Department.SECURITY.getDeptId());
	}
}

Output:
Accounts dept id:12
HR dept id:24
Security dept id:108

Prevent a method from being overridden
By specifying final keyword to the method you can avoid overriding in a subcalss. Similarlly one can use final at class level to prevent creating subclasses.
