Finding length of all values in an ArrayList

For a program I'm attempting to have a nested for loop repeat along the lines of this:

for(int i = 0;i < ArrayList.size();i++){
    for(int x = 0;x <ArrayList.get(i).length();x++){
        //stuff
    }
}

Essentially I want to repeat a for loop for every character in every index of an ArrayList but this solution doesn't seem to work. Any help appreciated!

Edit: the arraylist will only contain strings in my case

Solution

  • Try using a For Each Loop such that:

    int sumLength = 0;
ArrayList<String> r = new ArrayList<String>();
for(String s : r)
{
 sumLength += s.length();
}
return sumLength;

    That will give you the sum of all the lengths in your ArrayList
