StringBuilder and StringBuffer classes have not overridden hashcode() and equals() methods.And it’s because they are mutable, and their primary use is for constructing strings.If we need to compare content,we can call StringBuffer#toString() or StringBuilder#toString() and compare the returned ...

Although, StringBuilder and StringBuffer classes can be used for mutable sequences of characters in Java, they have a key difference. Unlike StringBuffer class, StringBuilder class is not thread-safe, and provides no synchronization. Therefore, it is recommended that the StringBuilder class should be...
java.lang.StringBuffer线程安全的可变字符序列。一个类似于 String 的字符串缓冲区,但不能修改。虽然在任意时间点上它都包含某种特定的字符序列,但通过某些方法调用可以改变该序列的长度和内容。可将字符串缓冲区安全地用于多个线程。可以在必要时对这些方法进行同步,因此任意特定实例上的所有操作就好像是以串行顺序发生...
