What all do I need to do to fix my mistakes

Answer 1

What exactly happens after you type "java Mirabella.class"? Are you getting an error message?

If nothing is ever returned, in other words your command prompt just blinks at you, it could be that you have an infinite loop and you're not outputting anything, or your program stops and waits for input that's never provided. Or it could be that you're program is running and exiting and you don't realize it because you have not output anything.

Answer 2

You need to specify the classpath. If all classes are in the current directory then type: java -cp . Mirabella

The "-cp ." is important so that the JVM knows where to look for the classes. Also you should not specify the ".class" extension. Good luck.

Answer 3

in your Mirabella.java code, have you defined a package?

If yes, you will need to provide the package name to run the code.

for example, if package name is com.trial.program then after compiling, you can run it as

java com.trial.program.Mirabella

If this is not the case, please give the error you get when you run java Mirabella.class
