length of each element in an array Java

Question

Here is what I\'m trying to use. The method .length doesn\'t work for anything I try, so I\'m not even sure where to begin.

import java.util.ArrayList;

public c         


        

Answer 1

You are trying to iterate through a single int instead of the strings array. Change

for (int nums: lengthList) {
    System.out.println(nums.length());  
}

to

for (String str: list) { // loop through the list of strings
    lengthList.add(str.length()); // store the individual length of each string
}

so as to loop through the list of strings, collect the length of each string & store it int the Arraylist that you return later.
