It happens because your class is not in your classpath.<br />
You need to include the directory that contains your class in you classpath.<br />
<br />
eg. if your class file is in c:\javastuff\test.class<br />
<br />
then use:<br />
<br />
java -classpath c:\javastuff test<br />
<br />
or if you are in the same directory as the classpath you can use:<br />
<br />
java -classpath . test

Java is a platform-independent, object-oriented programming language and run-time environment, designed to have as few implementation dependencies as possible such that developers can write one set of code across all platforms using libraries. Most devices will not run Java natively, and require a run-time component to be installed in order to execute a Java program.
