String Split - Calculate length of individual splitted parts

Question

For a string like :

String strTest = '123456.78';
system.debug(StrTest.split('\\.'));

The result is

USER_DEBUG [2]|DEBUG|(123456, 78)

How can I get the individual length of the splitted parts ?

Answer 1

The string split() method returns a List<String>, so getting the individual lengths is simply

1. Iterating over the returned list
2. calling string.length() on the individual strings

Answer 2

Here you go. Logic is same as Derek's answer

String strTest = '123456.78';

List<String> str = strTest.split('\\.');

for(integer i=0;i<str.size(); i++)
{
    System.debug(str[i].length());
}
