I'm not able to run my algorithms in Java through the Windows 8.1 terminal.

It happens that always gives a class error not found, I already put the .class files together with .java and still can not find.

What do I do to resolve?

Here are some pictures to illustrate my doubt.

PS: I have already used the command javac sistema.java pessoa.java aluno.java and NOTHING.

To compile the classes you must save the class with the same name as you will use to call the class by cmd.

public class HelloWorld {

    public static void main(String[] args) {
        System.out.println("Hello, World");
    }
}

You should call cmd this way:
javac HelloWorld .java

It is possible to name a class with any name supported by the language. But it is interesting to follow some rules adopted:

Each class must begin with a capital letter, if a class name consists of more than one word, the first letter of each word must be uppercase. Do not declare a class with any special characters (@, #, $,%, & amp ;, *, _, etc ...). The selected word should reflect the purpose of the class.

Always place the class in some package.
