can I write two public class in a java file?

qdxby

I found I can't write two public class in a java file,only 1 public class is allowed in a java file,and the name of the public class is the name of the java file.

Is it right?

So,I have a question now:

if a class2 in  java file2 wants to uses a class1(not public) in java file1,how can class2 access  class1?

thanks for any hint

Generally speaking, they need to be in the same package. If class1 you mentioned is a inner class, it'll be more complex.

因为公共类是在包中共享的，java调用类应该是基于文件名的，所以一个文件只能是一个public类。

其实除了公共类可以在包内被访问，还有默认的，保护的 都是可以被访问的，
而且java调用类是基于编译后.class文件文件名
