A Java class file is a file (with the .class filename extension) containing Java bytecode that can be executed on the Java Virtual Machine (JVM).A Java class file is usually produced by a Java compiler from Java programming language source files (.java files) containing Java classes (alternatively, other JVM languages can also be used to create class files).
Java is a high-level, class-based, object-oriented programming language that is designed to have as few implementation dependencies as possible. It is a general-purpose programming language intended to let programmers write once, run anywhere (), [16] meaning that compiled Java code can run on all platforms that support Java without the need to recompile. [17]
The Java class loader, part of the Java Runtime Environment, dynamically loads Java classes into the Java Virtual Machine. [1] Usually classes are only loaded on demand . The virtual machine will only load the class files required for executing the program. [ 2 ]
If a class does not specify its superclass, it implicitly inherits from java.lang.Object class. Thus all classes in Java are subclasses of Object class. If the superclass does not have a constructor without parameters the subclass must specify in its constructors what constructor of the superclass to use. For example:

Classes can be derived from one or more existing classes, thereby establishing a hierarchical relationship between the derived-from classes (base classes, parent classes or superclasses) and the derived class (child class or subclass) . The relationship of the derived class to the derived-from classes is commonly known as an is-a relationship. [21]
Classes in an unnamed package cannot be imported by classes in any other package. [3] The official Java Tutorial advises against this: Generally speaking, an unnamed package is only for small or temporary applications or when you are just beginning the development process. Otherwise, classes and interfaces belong in named packages. [4]
The classpath tells Java where to look in the filesystem for files defining these classes. The virtual machine searches for and loads classes in this order: bootstrap classes: the classes that are fundamental to the Java Platform (comprising the public classes of the Java Class Library , and the private classes that are necessary for this ...
