What is the method of splitting the string split

This article introduces the relevant knowledge of "what is the method of segmenting string split". In the operation of actual cases, many people will encounter such a dilemma, so let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

Several times I tried to split the string without success, and I didn't find the reason.

The string is as follows: aaa | bbb | ccc | ddd.

It is separated by a vertical bar, and the previous segmentation is like this: aaa;bbb;ccc;ddd.

Such a string is directly like this.

String [] resArr=res.split (";")

Segmentation is successful, but like a string separated by a "|", it doesn't work in the same way.

I tried other character segmentation to see if I would encounter the same problem when splitting strings with other symbols.

Sure enough, when I use English dots. It is as unsuccessful as the vertical bar, but there are also other symbols, such as "$", "[" and so on. I've tried a lot and I've found these so far.

I fumbled and solved the problem by using the following method, that is, when syncopating, I escaped the symbol and added two prime.

Public class Demo01 {public static void main (String [] args) {String res= "U2032 | AAAAAAA | 4218710000000277 | 1"; / / it is useless for String [] resArr01=res.split ("|"); String [] resArr=res.split ("\ | |"); for (String string: resArr) {System.out.println (string);}

Later, I tried again, some symbols that do not need to escape, such as the semicolon ";", can still be segmented successfully by adding two apostrophes.

So to be on the safe side, add two skimmers.
