About Me

Hello, I am Naresh Joshi and I welcome you to Java By Source. Java By Source is a friend to Java programming and Java related technologies and frameworks like Spring, Hibernate, Struts, Web Services, Micro Services, Design Patterns, Multithreading, Collection, XML, SQL.


I love to create my own thoughts about anything which comes to my notice and I think we should always have our own thinking on everything rather than just following what others think.

That’s why I have started writing this blog to keep all my research notes and my thoughts regarding Java programming language in one place and make them available to others.

Thanks for visiting Java By Source and I hope you enjoyed the posts. Any kind of feedback is always welcomed and appreciated. You can submit any query or suggestion in the Contact Us box (Bottom Right). You can also reach me on LinkedIn or Facebook or Github.

Java Cloning - Copy Constructor versus Cloning

In my previous article Java Cloning and Types of Cloning (Shallow and Deep) in Details with Example , I have discussed Java Cloning in details and answered questions about how we can use cloning to copy objects in Java, what are two different types of cloning (Shallow & Deep) and how we can implement both of them, if you haven’t read it please go ahead. In order to implement cloning, we need configure our classes to follow below steps Implement Cloneable interface in our class or its superclass or interface, Define clone() method which should handle CloneNotSupportedException (either throw or log), And in most cases from our clone() method we call the clone() method of the superclass. And super.clone() will call its super.clone() and chain will continue until call will reach to clone() method of the Object class which will create a field by field mem copy of our object and return it back. Like everything Cloning also comes with its advantages and disadvantages. However, Java c...

Creating objects through Reflection in Java with Example

In Java, we generally create objects using the new keyword or we use some DI framework e.g. Spring to create an object which internally use Java Reflection API to do so. In this Article, we are going to study the reflective ways to create objects. There are two methods present in Reflection API which we can use to create objects Class.newInstance() → Inside java.lang package Constructor.newInstance() → Inside java.lang.reflect package However there are total 5 ways create objects in Java, if you are not aware of them please go through this article 5 Different ways to create objects in Java with Example . Both Class.newInstance() and java.lang.reflect.Constructor.newInstance() are known as reflective methods because these two uses reflection API to create the object. Both are not static and we can call earlier one on a class level object while latter one needs constructor level object which we can get by using the class level object. Class.newInstance() The Class class is th...

Everything About Method Overloading Vs Method Overriding

In a previous article  Everything About ClassNotFoundException Vs NoClassDefFoundError , I have explained ClassNotFoundException and NoClassDefFoundError in details and also discussed their differences and how to avoid them. If you have not read it, please go ahead and give it a look. Similar to that here in this article, we will look into one more core concept of Java which is method overloading and overriding. As soon as we start learning Java we get introduced to them and their contracts which are pretty simple to understand but sometimes programmers get confused between them or they do not know either it is a correct overload/override because of the different rules. Here we will discuss What is method overloading and overriding, What contract one must follow to correctly overload or override a method, What are the different rules of method overloading and overriding and what are the differences between them. Method Overloading Method overloading means providing t...
