D ReplacementWords.java X 1/* 2 Write a program that replaces words in a sentence. The input begins with an integer indicating the number of word replacement 3 pairs (original and replacement) that follow. The next line of input begins with an integer indicating the number of words in 4 the sentence that follows. Any word on the original list is replaced. Assume that the list will always contain less than 20 word replacement pairs. 5 6 7 8 9 Ex: If the input is: 3 automobile car manufacturer maker children kids 10 15 The automobile manufacturer recommends car seats for children if the automobile doesn't already have one. 11 then the output is: 12 13 The car maker recommends car seats for kids if the car doesn't already have one. 14 You can assume the original words are unique. For coding simplicity, follow each output word by a space, even the last one. 15 16 Hint: For words to replace, use two arrays: One for the original words, and the other for the replacements. 17 18 Your program must define and call the following method that returns index of word's first occurrence in wordlist. If not 19 found, the method returns -1. 20 public static int findWordInWordList(String[] wordList, String wordToFind, int numInList) 21 */ 22 23 package methods Continued; 24 25 import java.util.Scanner; 26 27 public class ReplacementWords { 28 290 public static int findWordInWordList(String[] wordList, String wordToFind, int numInList) { 30 31 for (int i = 0; i ReplacementWords [Java Application] C:\Program Files\Java\jdk-14.0.1\bin\javaw.exe (Jan 7, 2021, 7:02:41 PM - 7:02:43 PM) automobile car manufacturer maker children kids 15 The automobile manufacturer recommends car seats for children if the automobile doesn't already have one.
