[Solved] Java – Split string with multiple dash

by


Well, many down votes but I’ll add a solution

the most efficient way to do that is using java.lang.String#lastIndexOf, which returns the index within this string of the last occurrence of the specified character, searching backwards

lastIndexOf will return -1 if dash does not exist

String str = "first-second-third";
int lastIndexOf = str.lastIndexOf('-');
System.out.println(lastIndexOf);
System.out.println(str.substring(0, lastIndexOf)); // 0  represent to cut from the beginning of the string

output:

12

first-second

4
