Hola quizas suene repetitivo este problema, pero voy empezando hoy en java, baje el compilador j2sdk1.4.2, agrege a las variables de entoro el path y la classpath.
Tengo mi programa en note pad llamado prueba.java el cual se los muestro enseguida y pues al compilarlo en una consola de ms-dos me sale el siguiente error:
EXCEPTION IN THREAD "MAIN" JAVA.LANG.NoClassDefFoundError prueba/java
no se que pueda ser, si pudieran orientarme se los argadeceria mucho.
