A class is a blue print from which individual objects are created. A class can contain fields and methods to describe the behavior of an object.
The classloader is a subsystem of JVM that is used to load classes and interfaces. There are many types of classloaders e.g. Bootstrap classloader, Extension classloader, System classloader, Plugin classloader etc.
A class can consist of Local variable, instance variables and class variables.
Variables defined inside methods, constructors or blocks are called local variables. The variable will be declared and initialized within the method and it will be destroyed when the method has completed.
Instance variables are variables within a class but outside any method. These variables are instantiated when the class is loaded.
