Implementation of string Segmentation and transfer Array in JavaString

This article mainly talks about "the implementation of JavaString string segmentation to array", interested friends may wish to have a look. The method introduced in this paper is simple, fast and practical. Next let the editor to take you to learn the "JavaString string segmentation to the implementation of the array" it!

In our daily development, we often encounter splitting a string according to a specified character.

At this point, we often think of using str.split (",") to process the split array.

However, using the split () method requires transfer when splitting special characters. Such as the decimal point.

Below, I would like to recommend a method that can be separated without escape.

Use delimitedListToStringArray (str,delimiter) in org.springframework.util.StringUtils

Conduct a test

Public static void main (String [] args) {String str = "aa.bb.cc.dd.ee.ff"; System.out.println ("split uses'.' Split: "+ Arrays.toString (str.split (". ")); System.out.println (" split uses escaped'. Split: "+ Arrays.toString (str.split ("\\. ")); System.out.println (" StringUtils.delimitedListToStringArray uses'.' Split: "+ Arrays.toString (StringUtils.delimitedListToStringArray (str,". "));}

Running result

Split uses'.' Segmentation: [] split uses escaped'\.' Split: [aa, bb, cc, dd, ee, ff] StringUtils.delimitedListToStringArray uses'.' Split: [aa, bb, cc, dd, ee, ff]

At this point, I believe you have a deeper understanding of "the implementation of JavaString string segmentation to array". You might as well do it in practice. Here is the website, more related content can enter the relevant channels to inquire, follow us, continue to learn!
