I have code:
xxxxxxxxxx1
// split by underscore2
String[] text1 = "1593521967367_image.jpg".split("_");3
System.out.println(text1[0]); // 15935219673674
5
// minus sign by underscore6
String[] text2 = "1593521967367-image.jpg".split("-");7
System.out.println(text2[0]); // 1593521967367It works ok, but is it possible to have 1 split by "_" or "-" character, instead of 2 separated splits?

We can use regex in String split method.
Regex which solves the problem:
xxxxxxxxxx1
// regex with OR: "_|-"2
String[] text1 = "1593521967367_image.jpg".split("_|-");Full working example:
xxxxxxxxxx1
public class Example {2
3
public static void main(String[] args) {4
5
// split by underscore6
String[] text1 = "1593521967367_image.jpg".split("_|-");7
System.out.println(text1[0]); // 15935219673678
9
// minus sign by underscore10
String[] text2 = "1593521967367-image.jpg".split("_|-");11
System.out.println(text2[0]); // 159352196736712
}13
}String.split method takes regex as argument:
xxxxxxxxxx1
public String[] split(String regex)
