Could not find or load main class test

Question

I have already come across this error. I couldn't figure out today also.

   package com.example.cassandra;

   public class test
   {
     public static void main(String[] a)
     { 
        System.out.println("test");
     }
   }

This is my java file. My working directory is

  com/example/cassandra

Compile command is

  javac test.java

Changed working directory to parent directory of com

  cd ../../..

Run command

  java test

Says

  could not find or load main class test

Any body please explain what's the problem here?

Not conflicting, look carefully at the command lines they run along with their current directories and package names, and on your machine, `cd` to the parent of `com` and try running this command. — nanofarad, Feb 25 '15 at 11:36
you have missed static keyword in main() functions definition — V__, Feb 25 '15 at 11:37

You will need to actually specify the package name:

java com.example.cassandra.test

@GopsAB Not conflicting, look carefully at the command lines they run along with their current directories and package names, and on your machine, `cd` to the parent of `com` and try running this command. They're running it inside the package folder, which is wrong. – nanofarad Feb 25 '15 at 11:36
@GopsAB Just try it and see. – nanofarad Feb 25 '15 at 11:37
@GopsAB: No conflict at all - in the answer there, the OP was advised to run `java test.test` which is again the fully-qualified classname. – Jon Skeet Feb 25 '15 at 11:37
@hexafraction thanks. `Exception in thread "main" java.lang.NoClassDefFoundError: com/example/cassandra/test (wrong name: org/example/cassandra/test) at java.lang.ClassLoader.defineClass1(Native Method)` I tried the suggested one here and i got this error. But test.class is present in the specified directory – Gibbs Feb 25 '15 at 11:39
