How can we obtain the substring before a character in Java?
Suppose we have this string.
String str = "name:description";
We want to obtain
name, before the colon
We can use the
split() method to do this.
String splitted = str.split(":"); // ["name", "description"]
This will give us an array of strings containing the substrings around the given delimiter, which is a colon in this case.
We can then obtain the first element of the array, which will be
splitted // "name"
Revise the code and make it more robust with proper test case and check an error there before implementing into a production environment.
