Hi Friend,
No, you can't. It is necessary to save the java file with its class name otherwise it will give error.
Thanks

File name : Sample_File.java
class Sample { public static void main(String args[]) { System.out.println("This is a program with class name and file name are different"); } }
when I run this program as javac Sample_File.java java Sample
I am getting the output without any error.

no. its possible , we can run a program,Assume that my class name is A and file name is Afile.java.
While running a program , 1st type in command prompt(cmd) as
javac Afile.java
To run the progran
java A
surely it will run.

From Compiler point of view it is only the class name that matters rather than host specific source file name.
Normally, java compiler creates the .class file of any java file with its class name and .class extension. i.e., If we have a java source file with name 'Sample123.java' and the class name in that file is 'Sample' then the compiler would create a class file with name 'Sample.class'.
Java Specification:
NormalClassDeclaration: ClassModifiersopt class Identifier TypeParametersopt Superopt Interfacesopt ClassBody
The Identifier in a class declaration specifies the name of the class.
