Код собирается, но при этом выдаёт ошибку Error: Could not find or load main class

Не могу понять, почему код собирается но при этом пишет ошибку что не видит главного класса, хотя сам класс "мейн" присутствует в коде.

Вот вывод

C:\mita\Test_kod>javac ModifyXMLFile.java

C:\mita\Test_kod>java -classpath . ModifyXMLFile.class
Error: Could not find or load main class ModifyXMLFile.class

Попробовал вот так, но, увы не вышло :

C:\mita\Test_kod>java -mainpath . DOMxmlEdit.class
Unrecognized option: -mainpath
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.

C:\mita\Test_kod>java -classpath main DOMxmlEdit.class
