Basically, there are two main causes:

The first likely cause is that you may have provided the wrong class name. (Or ... the right class name, but in the wrong form.)

The second likely cause is that the class name is correct, but that the java command cannot find the class. To understand this, you need to understand the concept of the "classpath". This is explained well by the Oracle documentation:

http://docs.oracle.com/javase/7/docs/technotes/tools/windows/java.html

Setting classpath:

The Java Tutorial - http://docs.oracle.com/javase/tutorial/essential/environment/paths.html
