The default access modifier in Apex is private, while in Java, it is the default. The public in Java is not the same as the public in apex.
The public in Apex means any Apex can use the method or variable in this application or namespace. If you want to make something public like it is in Java, you need to use globally. If you want to be a freelance Apex developer, you need several years of experience with Oracle Application Express and writing code. Also, having experience with Java will help you a lot.
