Can't execute the Java code from the command line in Notepad++

[JProgrammer]

I have the program written correctly, but it won't execute.

public class Welcome {
public static void main(String[] args){
//Display message Welcome to Java! on the console
System.out.println("Welcome to Java");
}
}

I compiled the code as written below with "javac Welcome", and use the "Class" name "Welcome"
The file path is: C:\Java Programs

Javac Welcome.java
Java Welcome

Below is the result of the above commands

javac Welcome
Create Process() failed with error code 2:
The system cannot find the file specified.

java Welcome
Process started >>>
Error: Could not find or load main class Welcome
<<< Process finished. (Exit code 1)

Somebody Please Help Me! I am coding in notepad++

The first use shown of the javac command works but the second use does not. Notice the difference between the args to the command: the first has the extension: .java, the second does not hava .java
