Split using the split Function

1. When multiple spaces exist, the following conditions are met:

String S = "keyword"; string [] array = S. split ("\ s +"); For (string L: array) {system. out. println (L + "");}

\ S indicates space, carriage return, line feed, and other blank characters. + indicates one or more spaces.

Extended, \ D represents 0-9 numbers; \ W represents characters, numbers, letters or underscores;

These are Java Regular Expressions

2. When there are multiple delimiters:

String S = "I love you, mother! "; String [] arraytemp = S. Split (" |, "); For (string L: arraytemp) {system. Out. println (L + "");}

Add a vertical line in the middle to split multiple separators.

3. When used | ,[,\,.,*,? , And other special characters to be separated, escape, such as S. Split ("\ | ");
