Java - Problema con ClassLoader

La clase Main me da los siguientes errres de ejecución:
at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:301)
at java.lang.ClassLoader.loadClass(ClassLoader.java:252)
at java.lang.ClassLoader.loadClassInternal(ClassLoader.java:320)
Could not find the clase1class: javaapplication1.Main. Program will exit..
¿Por qué?
¿Cómo se souciona?
Codigo
