This java tutorial shows how to use the valueOf(Object obj) method of String class of java.lang package. This method returns a string representation of the Object obj specified as method argument. To make it simple it is only simple call to the Object.toString() method.

Java is an object-oriented programming language. Everything in Java is associated with classes and objects, along with its attributes and methods. For example: in real life, a car is an object. The car has attributes, such as weight and color, and methods, such as drive and brake.

I Java ärver alla klasser egenskaper från klassen Object (dvs. alla klasser som själva inte är Object). Object sägs då vara en superklass.

Summing up, classes and objects in java are the preliminary concepts of Object Oriented Programming in Java and a good concept of classes is essential for future development. Classes come in handy when we need to develop datatypes of our own. So, it is important that we have a deep understanding of the topic before moving on.

The Java™ Object Heap (Java Heap) stores Java objects, including instances of classes and the data that the objects contain, such as primitives and references. This extension aims to increase developer productivity by allowing you to generate Plain old java object from a well defined JSON string.
