以下是一个示例代码: importorg.apache.commons.lang3.StringUtils;Stringstr="Hello World";intsizeInBytes=StringUtils.getBytesUtf8(str).length;System.out.println("字符串的字节大小为:"+sizeInBytes); 1. 2. 3. 4. 5. 这段代码首先使用StringUtils类的getBytesUtf8()方法将字符串"Hello World"转换为字节...
AI代码解释 CONSTANT_Utf8_info{u1 tag;u2 length;u1 bytes[length];} 其中u2是一种类似于Java中int一样的数据类型,只是表示的是一个 2 个字节的数据类型,只不过int是 4 个字节,这也就意味着允许的最大长度为65535个字符。所以我们可以得出一个结果,当字符串存放在栈内存中的时候,字符串的长度可以达到 65535。

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 size of a wide string...
