Examples of GoF Design Patterns in Java's core libraries
that java.lang.Object#toString() is example of factory pattern.
I am confused about this.
What i have understood till now is that factory pattern is used to create objects .
Can someone explain it more clearly?
In essence, the factory pattern is an abstract class or interface that specifies a method to produce something. Then you have an implementation and from that implementation, you can build that something.
Here we have:
Abstract class or interface: Object
Build method: toString()
Implementation: Any java object
Product: A string
So yeah, it is a bit of a strange example and there are better ones out there, but it does fit the model for a factory.
