1.虽然String、StringBuilder、StringBuffer都是以char数组value来存字符串,但是String中value是final的(即构造方法初始化后无法被修改),而其余两个却没有,所以再做拼接时,String需要不停的新建String对象,并用copy方法来实现拼接,而StringBuilder、StringBuffer则可在value容量足够情况下在value后拼接字符串; 二、成员方法...
And in multithreading, you can't use safely a StringBuilder. Here is my test (not a benchmark, just a test) : public static void main(String[] args) { String withString =""; long t0 = System.currentTimeMillis(); for (int i = 0 ; i < 100000; i++){ withString+="some ...
