Write a function listLengthOfAllWords which takes in an array of words (strings), and returns an array of numbers representing t

vesna_86 [32]

Answer:

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

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

for (int i=0; i<intArray.length; 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<wordArray.length; i++){

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

intArray[i]=lenOfWord;

}

return intArray;

}

}

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

Differences between windows xp and windows vista

krek1111 [17]

Well since Windows XP runs on Windows 2000 technology,it would be "slow".Also that Windows XP had MSN,which expired 15 years ago,but the good thing about Windows XP is that it can connect to the internet via WiFi without the computers hardware used for WiFi(PC only).Also that Windows XP has a logo on the start-up screen.Windows Vista on the other hand, doesn't have a logo on the start-up screen,but shows a Windows Vista animated logo atfer the start-up screen.Also that some people named Windows Vista "The first Windows 7".But somewhat,Windows Vista ran faster than Windows XP at starting up.Windows Vista was old,but it sold better than Windows XP.
