The Java programming language requires that identical string literals (that is, literals that contain the same sequence of code points) must refer to the same instance of class String. In addition, if the method String.intern is called on any string, the result is a reference to the same class instance that would be returned if that string appeared as a literal.
Having written about Java serialization previously, I thought I’d put in some research into the concept of ‘Marker Interfaces’ or ‘Tag Interfaces’. Well, getting matters straight, technically, the word ‘Marker’ is an invention of bloggers and technical writers. Java specification says nothing about an interface being a ‘Marker Interface’. You won’t find the word ‘Marker’ at all..
The beauty about JavaScript is that every single thing you see in JavaScript is an object. Isn’t is beautiful, a variable,string,number or even a method is an object. So, whenever you say ‘Object’, what comes to your mind is ‘properties’ and ‘methods’. An example speaks louder than 20 lines, so here goes..
Classloaders are pivotal in the lifecycle of a JVM. This a look into how they work.
One of the most interesting corners in ‘Java World’ is serialization. Serialization provides the developer with the ability to store an object’s state in memory, or converting the object to a stream of binary digits, and stored in memory.
