如果一个对象在Java中不包含可以更改的实例变量并且没有静态变量，那么它是否可以安全地用Java进行线程安全？

Totally safe, as long as it does not extend a non thread-safe class.

If an object is stateless, it can safely be shared by several threads.

That is also why it is encouraged to use immutable objects in multi-threaded environment as their state cannot be concurrently modified.
