A singleton is a class for which only one instance can exist
within a program. In other words, only one, single object of
that particular class can be created in a program.

Answer / naman patidar
A singleton class can never have more then one instance.
Example :
class SingletonClass {
private static SingletonClass singleObject;
public static SingletonClass getInstance() {
if (singleObject == null) {
singleObject = new SingletonClass();
}
return singleObject;
}
}
