public static int[] listLengthOfAllWords (String [] wordArray) {

int[] intArray = new int[wordArray. length];

for (int i=0; i
int lenOfWord = wordArray[i]. length ();

intArray[i]=lenOfWord;

}

return intArray;

}

Explanation:

Declare the method to return an array of ints and accept an array of string as a parameter within the method declare an array of integers with same length as the string array received as a parameter. Iterate using for loop over the array of string and extract the length of each word using this statement int lenOfWord = wordArray[i]. length (); Assign the length of each word in the String array to the new Integer array with this statement intArray[i]=lenOfWord; Return the Integer Array

A Complete Java program with a call to the method is given below

import java. util. Arrays;

import java. util. Scanner;

public class ANot {

public static void main (String[] args) {

String []wordArray = {"John", "James", "David", "Peter", "Davidson"};

System. out. println (Arrays. toString (listLengthOfAllWords (wordArray)));

}

public static int[] listLengthOfAllWords (String [] wordArray) {

int[] intArray = new int[wordArray. length];

for (int i=0; i
int lenOfWord = wordArray[i]. length ();

intArray[i]=lenOfWord;

}

return intArray;

}

}

This program gives the following array as output: [4, 5, 5, 5, 8]
