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

Use following code:

public static List lengths(List list) {
    List lengthList = new ArrayList();
    for (String nums: list) {
        int len = nums.length();
        lengthList.add(len);
        System.out.println(len);  
    }    
    return lengthList;
}
