为什么在Java中将String设计为Class / Object，这会使用更多资源

Question

Well, String is an often used type, working as an Object consumes more resource, why Sun designed it as an Object but not a simple variable like int

if someone says String can contain very long sentence, why it was not designed to be like int and Integer

Answer 1

There are some advantage of being an Object instead of primitives

1. No size limit
2. you can implement utility methods for helping operations
3. you can make it immutable

Answer 2

如果您想更有效地将文本存储在内存中，可以将其保存在字节数组中。
