Get the substring before the last occurrence of a separator in Java
We have the following string with a separator.
String str = "David-Warner";
We want the substring before the last occurrence of a separator. Use the lastIndexOf() method.
For that, you need to get the index of the separator using indexOf()
String separator ="-"; int sepPos = str.lastIndexOf(separator); System.out.println("Substring before last separator = "+str.substring(0,sepPos));
The following is an example.
Example
public class Demo { public static void main(String[] args) { String str = "David-Warner"; String separator ="-"; int sepPos = str.lastIndexOf(separator); if (sepPos == -1) { System.out.println(""); } System.out.println("Substring before last separator = "+str.substring(0,sepPos)); } }
Output
Substring before last separator = David
