I am trying to search a string for the last index of a capital letter. I don't mind using regular expressions, but I'm not too familiar with them.

int searchPattern = searchString.lastIndexOf(" ");      
String resultingString = searchString.substring(searchPattern + 1);

As you can see, with my current code I'm looking for the last space that is included in a string. I need to change this to search for last capital letter.


You can write a method as follows:

public int lastIndexOfUCL(String str) {        
    for(int i=str.length()-1; i>=0; i--) {
        if(Character.isUpperCase(str.charAt(i))) {
            return i;
        }
    }
    return -1;
}

how to search for a capital letter within a string and return the list of , Split the string into a list where each item is a separate word. For every word in that list, iterate through and check for capital letters (consider the string constants such as string. uppercase). If it has a capital letter, insert it onto the front of your result list. In order to find number of uppercase letters in a string of all capital letters in a string we need to iterate all characters of a string in a loop and check individual characters are uppercase letters or not using Character class provided isUpperCase() method. package findUppercaseletters.String;


Pattern pat = Pattern.compile("[A-Z][^A-Z]*$");
Matcher match = pat.matcher(inputString);

int lastCapitalIndex = -1;
if(match.find())
{
    lastCapitalIndex = match.start();
}

lastCapitalIndex will contain the index of the last capital letter in the inputString or -1 if no capitals exist.

EDIT NOTE: Solution formerly contained a loop, now it will work with one call to find() and no looping thanks to an improved regex. Tested new pattern as well, and it worked.
