Problema: se lo eseguo in netbeans funziona perfettamente; ma con "java Testexam" mi da questo:

Exception in thread "main" java.lang.NoClassDefFoundError: Testexam (wrong name:

???????????????????????????????????????


PS. Venerdì ho l'esame d java quindi se avete consigli dite pure

[PGI]

ad occhio (dal msg d'errore) direi che la classe appartiene ad una package (Pratica) ragion per cui dovresti posizionarti nella cartella immediatamente superiore a "pratica" e lanciare il programma con il comando

java Pratica.Testexam

Ora funge!
