You should also point out (I know I will get flamed for this ;-)) that the only time you do not want to use "public" is in inner classes (which in my opinion should be outlawed anyways)

Do you really mean just inner classes? Would you ban all nested classes 
outright?

It would be a very, very boneheaded thing to outlaw inner classes. 
You'd destroy a common idiom for declaring listeners. You'd make lambdas 
impossible. You'd kill one of the most expressive features of Java, that 
was introduced to the language in the first place because of its great 
power.

You are aware that nested classes were added to Java, not there from the 
beginning, yes? There were excellent reasons to do that.

Study the matter.
