Question

This is a singleton class.

I wanted to know the ways to we break the singleton logic in this code

class Employee{ // class starts
    private Employee(){} // private constructor

    private static Employee emp; 
    /*static block*/

    static {    
        if (emp==null)
        {
            emp=new Employee(); 
        }
    }      
    /* static method*/          
    public static Employee getEmployee()
    {   
        return emp;  
    }
}

You should also do below in constructor to avoid object creation by reflection

private Employee(){ 
if(emp!=null){
   throws new InstantiationError("singleton breached ");
}

}
