7.6 lab: replacement words write a program that finds word differences between two sentences. the input begins with the first sentence and the following input line is the second sentence. assume that the two sentences have the same number of words. the program displays word pairs that differ between the two sentences. one pair is displayed per line. ex: if the input is: smaller cars get better gas mileage tiny cars get great fuel economy then the output is: smaller tiny better great gas fuel mileage economy hint: store each input line into a list of strings.

A program is a set of codes and or instructions that are written sequentially and deliberately such that the computer, when it reads and executes them give a specific and premedicated output.

The lines of code that gives the output described above is:

import java.util.Scanner; public class LabProgram {

public static int findWordInWordList(String[] wordList, String wordToFind, int numInList) {

for (int i = 0; i < numInList; i++) {

if (wordList[i].equals(wordToFind)) {

return i;

} } return -1;

} public static void main(String[] args) {

Scanner scnr = new Scanner(System.in);

String[] original = new String[20], modified = new String[20]; int numInList = scnr.nextInt();

for (int i = 0; i < numInList; i++) {

original[i] = scnr.next();

modified[i] = scnr.next();

} int numWords = scnr.nextInt();

String[] words = new String[numWords];

for (int i = 0; i < numWords; i++) {

words[i] = scnr.next();

} int index;

for (int i = 0; i < numWords; i++) {

index = findWordInWordList(original, words[i], numInList); if (index != -1)

words[i] = modified[index];

} for (int i = 0; i < numWords; i++) System.out.print(words[i] + " ");

System.out.println(); } }
