Java programming Make sure to use arrays and look at the requirements.





There is a fun childrens game where one child thinks of a common phrase, then the second child repeatedly makes guesses as to the letters that it contains. You are to write a Java program that: Prompts a user to enter a common phrase, and reads it into a variable using Scanner.nextLine() - under the assumption that the phrase consists of nothing but lowercase letters and spaces. A counter is set to zero. The following is than repeated until the entire common phrase is revealed: The common phrase is displayed with all of its letters (that have not been correctly guessed) replaced with the? character and all of the letters that have been correctly guessed displayed as is. The second user is then (repeatedly) asked to enter a single lower case letter - until they do. The counter is incremented. Once the common phrase is revealed, you must report the total number of (valid) guesses that were required to do so. Requirements Your program must implement and use the following methods: public static char [] initTemplateArray(String sPhrase)

Explanation / Answer

import java.util.Scanner;

public class Program09
{
public static void main(String[] args)
{
Scanner stdIn=new Scanner(System.in);
String cp;
char guess;
int space=0, consonant=0, vowel=0;

System.out.print("Please enter the phrase to guess at : ");
cp = stdIn.nextLine();
char template [] = new char [cp.length()];

space = initTemplateArray(cp, template);

printTemplateArray(template);
System.out.println();
guess = getConsonant(stdIn);
System.out.println();

consonant=updateTemplateArray(template, cp, guess);

while(!cp.equals(new String(template)))
{
printTemplateArray(template);
System.out.println();
String ans;
do
{
System.out.print("Would you like to buy a vowel : ");
ans = stdIn.next();

}while(!ans.equals("y") && !ans.equals("n"));

System.out.println();

if(ans.equals("y"))
{
guess = getVowel(stdIn);
vowel+=updateTemplateArray(template, cp, guess);
}
else if(ans.equals("n")) // readability
{
guess = getConsonant(stdIn);
consonant+=updateTemplateArray(template, cp, guess);
}

}

printTemplateArray(template);
System.out.println();
System.out.println("The common phrase contained: " + space + " space(s), "+ consonant +" consonsant(s) and "+ vowel +" vowel(s)." );
stdIn.close();
}

public static int updateTemplateArray(char [] tmpArr, String sPhrase, char guess)
{
int count=0, loc=sPhrase.indexOf(guess);

while(loc!=-1)
{
count++;
tmpArr [loc] = guess;
loc = sPhrase.indexOf(guess, loc+1);
}
System.out.println();
return count;
}

public static int initTemplateArray(String sPhrase, char [] tmpArr)
{
int space=0;
for(int i=0; i< sPhrase.length(); i++)
{
if(Character.isWhitespace(sPhrase.charAt(i)))
{
tmpArr[i] = ' ';
space++;
}
else
tmpArr[i]='?';
}
return space;
}

public static void printTemplateArray(char [] tmpArr)
{

System.out.println();
System.out.println("Common Phrase");
System.out.println("-------------");

for(int i=0; i<tmpArr.length; i++)
System.out.print(tmpArr[i]);

System.out.println();

}

public static boolean isVowel(char guess)
{
return(guess=='a'||guess=='e'||guess=='i'||guess=='o'||guess=='u');
}

public static char getVowel(Scanner stdIn)
{

String guess;

do
{
System.out.print("Enter a lowercase Vowel guess : ");
guess=stdIn.next();
}while(guess.length()!=1 || !(guess.charAt(0)>='a')|| !(guess.charAt(0)<='z') ||!isVowel(guess.charAt(0)));

return guess.charAt(0);
}

public static char getConsonant(Scanner stdIn)
{
String guess;

do
{
System.out.print("Enter a lowercase consonant guess : ");
guess=stdIn.next();
}while(guess.length()!=1 || !(guess.charAt(0)>='a')|| !(guess.charAt(0)<='z') ||isVowel(guess.charAt(0)));

return guess.charAt(0);
}


}
