StrlenWhat Strlen does is work on a counter that starts scanning from somewhere in memory (which can be the beginning of a string, somewhere in the middle, or even an indeterminate area of memory) until it touches the first string terminator, and then returns the counter value (length does not contain '% ').Refers to the actual length of the actual string or array of characters (not the number of bytes in the occupied space).Function prototypesextern unsigned int strlen (char *s)It means that he

If you are the designer of the JVM, and you decide to make a representation of all the characters in the JVM, will you not allow characters that are encoded in a variety of formats to coexist?
I guess your answer is no, if the Java characters in memory can exist in various encoding forms such as GB2312,UTF-16,BIG5, then for developers, even the most basic string printing, connection and other operations will be unable to do anything. For example, after a GB2312 string is attached to a UTF-8 str
