Today, I will talk to you about how to get the start position and end position of the string in Java. Many people may not know much about it. In order to make you understand better, the editor has summarized the following for you. I hope you can get something according to this article.

/ * get the start and end position of a string * * @ param v source string * @ param find to find the string * @ return array 0 = start position 1 = end position * / public static int [] getStringStartAndEndIndex (String v, String find) {int start =-1; / / start subscript int end =-1 / / ending subscript int currentIndex = 0; / / current subscript-1 equals the length of the current source string traversed char [] source = v.toCharArray (); / / Source string char array char [] target = find.toCharArray (); while (source.length > = currentIndex) {boolean result = true; for (int I = 0; I < target.length) ) {if (source [currentIndex] = = target [I]) {result = true;} else {result = false; currentIndex++; break;} currentIndex++ } if (result) {start = currentIndex-target.length; end = currentIndex; break;}} return new int [] {start, end};}

How to use it:

Public static void main (String [] args) {String v = "class method line"; / / returns an array where 0 is the start position and 1 is the end position char [] indexes = getStringStartAndEndIndex (v, "method") System.out.println ("start position:" + indexes [0] + ", end position:" + indexes [1]) } after reading the above, do you have any further understanding of how to get the beginning and end of a string in Java?
