如果放进String Pool的String非常多,就会造成Hash冲突严重,从而导致链表会很长,而链表长了后直接会造成的影响就是当调用String.intern时性能会大幅下降。 使用-XX:StringTablesize可设置StringTable的长度 在jdk6中StringTable是固定的,就是1009的长度,所以如果常量池中的字符串过多就会导致效率下降很快。StringTablesize...
Size of String Literals The size (in bytes) of a narrow string literal is the number of characters plus 1 (for the terminating null character); the size (in bytes) of a wide string literal is the number of characters times 2 plus 2 (for the terminating null character). This shows the...
