为什么字符串在java中以null字符终止？ [英] why strings are terminated with null character in java?

问题描述

今天我已经读过字符串在java中以null字符终止。但是为什么它是必要的，因为字符串的长度已经由sting类的长度变量维护了？所以这对我来说有点奇怪。请有人向我澄清。

Today I have read that strings are terminated with null character in java. But why is it necessary since length of the string is already maintained by the length variable of the sting class ? So it's kind of strange thing to me. Please someone clarify it to me.

谢谢

推荐答案

Java字符串不是空终止。它们以长度的长度结束。您可以将 \0 设置为Java字符串的最后一个字符，但这不会自动终止该字符串。 12< \0> 45 的长度仍然是5，而不是C中的2。

Java strings are not null terminated. They end with the length in length. You can make a \0 the last character of a Java string, but that doesn't automatically terminate the string. The length of 12<\0>45 would still be 5 and not 2 as in C.
