Is Empty .java file name a valid source file name?


Yes, Java allows to save our java file by .java only, we need to compile it by javac .java and run by java classname Let's take a simple example:

//save by .java only  
class A{  
public static void main(String args[]){  
System.out.println("Hello java");  
//compile by javac .java  
//run by     java A  

compile it by javac .java

run it by java A
