如果java中没有指定修饰符，会发生什么情况？

Question

 class BTNode
 {    
     BTNode left, right;
     int data;

     //constructors and methods
} 

在这段代码中，没有使用特定的修饰符。那么在修饰语的上下文中会发生什么呢？他们是否有任何默认行为

Answer 1

从Java文档：

If a class has no modifier (the default, also known as package-private), it is visible only within its own package (packages are named groups of related classes)
