The Java string.split (String regex) method sets multiple delimiters __java

We know that a string variable has a split method that is used to split a string string and return an array of string literals.
For example:

String str = "Hello,boy,what ' your name?";

At this point we need to use the comma (,) as the delimiter, the sentence is cut open, then using:

string[] Array = Str.split (",");

However, sometimes this happens:

String str = "1+2-3+5-64*25+25/65";

We need to use the + 、-、 *,/as the separator, cut the string, remove the operator, get the number.
Of course, there are also solutions, and we can use regular expressions to set multiple delimiters for the split method.
For example:

String str = "1+2-3+5-64*25+25/65";
string[] Array = str.split ("\\+|-|\\*|/");

That is, use | To connect our multiple delimiters (\ = escape character, and some characters need to be escaped).
