Initialization order example

Bipartite Graph

With this example we are going to demonstrate what happens when there are changes in the initialization order of classes. The steps of the example are described in short: We have created class A, with a constructor that gets an int val and prints it. We have also created class Cr. In the Cr we use the A constructor to ...

IdentityHashcode example

Bipartite Graph

With this example we are going to demonstrate how to get the identity hashcode of a File. Each class in Java inherits hashCode() method from Object class. The identity hashCode is the hashcode that the object of the class would return. In short, to get the identity hashCode of a File you should: Create a few new File instances, by ...

Comparing File objects using hashcode example

Bipartite Graph

This is an example of how to compare File objects using the hashcode. Each class in Java inherits hashCode() method from Object class. Comparing File objects using the hashcode implies that you should: Create a few new File instances, by converting the given pathname strings into abstract pathnames.  For each one of the files, use hashCode() API method of File. ...
