1. String类被final关键字修饰,意味着它不可被继承;;2. String的底层采用了final修饰的char数组,意味着它的不可变性;3. 实现了Serializable接口意味着它支持序列化;4. 实现了Comparable接口,意味着字符串的比较可以采用compareTo()方法,而不是==号,并且Sring类内部也重写了Object的equals()方法用来比较字符串相等...
String字符串作为一种引用类型,在Java中的地位举足轻重,也是代码中出现频率最高的一种数据结构,因此,我们需要像分析Object一样,将String作为一个topic,单独拿出来总结,这里面涉及到字符串的不可变性,字符串拼接、存储、比较、截取以及StringBuffer,StringBuilder区别等。
