No, you do not have to type the file extension if you want to include the file name. You only use file extension to make the specific file be able to be run by the program. Example: I want to make my file into a java program so i can use with a specific type of program which only runs java file i put .jav at the end of the title to make it from a text file to a java file.
They end with an extension .java Test.java would be a java source file. The contents of Test.java could be package xyz; import java.util.*; public class Test { ... ... .. . . }
You write the source code, in a text editor, or better in a special IDE. The source code should have the extension ".java". You can have several classes in the same file. Then you compile the class to bytecode; this creates a file with extension ".class".
To get rid of the Java lang no class deffound error, one must add the class or .jar file which contains this class into the Java classpath. When a Java class is run from the command line, one must add a dot (.)
