java - StringBuffer 的容量是多少？

Question

当我运行这段代码时:

StringBuffer name = new StringBuffer("stackoverflow.com");
System.out.println("Length: " + name.length() + ", capacity: " + name.capacity());

它给出输出:

Length: 17, capacity: 33

明显的长度与字符串的字符数有关，但我不确定容量是多少？StringBuffer 在重新分配空间之前可以容纳的字符数是多少？

Answer 1

参见:JavaSE 6 java.lang.StringBuffer capacity()

但是你的假设是正确的:

The capacity is the amount of storage available for newly inserted characters, beyond which an allocation will occur
