I was learning singleton design pattern and I did understand the concept. However, I have a doubt in the following code : -
class Token
{
private static int i = 5;
private static Token obj = new Token();
//Private Constructor
private Token()
{
}
//Returning the singleton object
public static Token getObject()
{
return obj;
}
public static int getValue()
{
return i;
}
}
public class TestMain
{
public static void main(String args[])
{
Token obj = Token.getObject();
System.out.println("Without object " + Token.getValue());
System.out.println("With object " + obj.getValue());
}
}
The instance variable i gets printed in both the cases -
Without object 5
With object 5
What is the difference between the two ways of getting instance variable and which one is recommended?
