Apache Harmony is the recent open source implementation of the Java runtime with class libraries and associated tools.
There are several types of Java technology. Some examples of Java software are Java ME, Java EE, Java SE, and Java Card. Java made the JAVA development kit for those that develop in Java. There is also Java Virtual machine and some class libraries. Java is also famous for its languages like Clojure, Beanshell, Groovy, Gosu, Rhino, Kotlin, JRuby, Scala, and Jython.
Java source files have the .java extension, compiled Java class files have the .class extension.
Java Native Interface JNI is an interface between java and applications and libraries written in other languages. As an example, JNI enables Java programs to use C libraries and also enables C programs to use Java classes.
The actions in a java class are called methods.

The exact same way you instantiate a class from any of the various Java libraries: by using the 'new' keyword. i.e MyClass A = new MyClass(); this forces the MyClass definition to run its Constructor method, and return an instance of object of type MyClass.
Java is defined by a specification and consists of a programming language, a compiler, core libraries and a runtime (Java virtual machine) The Java runtime allows software developers to write program code in other languages than the Java programming language which still runs on the Java virtual machine. The Java platform is usually associated with the Java virtual machine and the Java core libraries.

without class non of the folder can run so the java program should start in class we can use the class without object in java
What i know is java we will use compiler when it want to get class file(file with .class extension) from java file(file with .java extension).
We can't call a class. We always call a method in java.
Class
