What is the extension of Java code files?

 In the context of Java programming language, the extension for creating a java class is “.java”. During the process, you would need to name the file with the name of the class followed by the “.java” extension.

For instance, if you want to create a class whose name is “Myclass” the file should be named “Myclass.java”

Here is the example given

Public class MyClass {

    // Class content goes here

    Public static void main(String[] args) {

        System.out.println(“This is my Java class!”);

    }

}

When you will save the above code to your file, you will get the name of the file in “Myclass.java”. This “.java” extension would prefer that it be the java source code file.
