Explanation of Solution

Program code:

MadLib.java

//import the required packages

import java.io.*;

//define a class MadLib

class MadLib

{

//define a method intro()

private static void intro()

{

//create a string variable and initialize it

String msg = "This is a Mad-Lib game. I will prompt " +

"you for five words.\n";

//print the string

System.out.print(msg);

}

//define a method getInput()

private static String getInput(String msg) throws IOException

{

//create the object of BufferReader

BufferedReader stdin;

//initialize the object

stdin = new BufferedReader(new InputStreamReader(System.in));

//print the string msg

System.out.print(msg);

//return the line readed

return stdin.readLine();

}

//define a method printOutput

private static void printOutput (String noun1, String adverb, String noun2, String pronoun, String adj)

{

//create a string output and set the value

String output = "\nThree blind " + noun1 + ", \nThree blind " + noun1 + ", \nsee " + adverb +

        pronoun + " a thing in your life,\nAs three " + adj + " mice.";

//print output

System.out.println(output);

}

//define a main() method

public static void main(String[] args) throws IOException

{

//call the method intro()

intro();

//get the value for noun1

String noun1 = getInput("Enter a noun : ");

//get the value for adverb

String adverb = getInput("Enter a adverb : ");

//get the value for noun2

String noun2 = getInput("Enter a another noun : ");

String pronoun = getInput("Enter a pronoun : ");

//get the value for adj

String adj = getInput("Enter an adjective : ");

printOutput(noun1, adverb, noun2, pronoun, adj);

}

}
