int arrayCount = 0;
int asteriskCount = 0;
System.out.print("Enter a letter in word ");
do {
asterisksInWord = false;
boolean contain;
if (asteriskCount != 1) {
asteriskCount = 0;
for (char item : words[wordNumber].toCharArray()) {
contain = Arrays.asList(discoveredElements).contains(String.valueOf(item));
if (contain) {
System.out.print(item);
} else if (item == letter) {

}
The log of it's run is
Enter a letter in word **** > t
Enter a letter in word t**t > h
Enter a letter in word th*t > a
The word is that You missed 0 time(s)
Do you want to guess another word? Enter y or n >y
y
Enter a letter in word **** >
My question is why does it ignores first symbol 'y' when asking "Do you want to guess another word?".
I'tried to create some test programs with same do-while conditions but they don't ask for character 2 times like that program.
The program asks for your input two times, because you have programmed it like that. After printing - "Do you want to guess another word? Enter y or n >" - you do input.nextLine() inside the while condition as well as as the first statement after do , so it asks for input twice.
Maybe you can move the question Enter the letter in the word to the inner do loop instead of doing that in the if condition if (asterisksInWord) { .
Also, according to your current logic, it does not ignore your first symbol, that is the real one that decides whether to exit the loop or not, the next input is actually your first guess.
I am Writing a game/java program that needs to take a word from a .txt file, then jumble the letters up and ask the user to guess what word it is. I am having two problems:
First is that I receive this error message when I run it:
Exception in thread "main" java.util.NoSuchElementException: No line found
at java.util.Scanner.nextLine(Unknown Source)
at Proj4.main(Proj4.java:20)
The second problem I am having is jumbling the word. I cannot figure out how to do that without using the shuffle command (which I cannot use).
Here is my code:
import java.util.Scanner;
import java.util.Random;
import java.io.*;
public class Proj4 {
public static void main(String[] args) throws IOException {
Scanner inFile = new Scanner(new File ("words.txt"));
int counter = 0;
while (inFile.hasNext()) {
inFile.nextLine();
counter++;
}
String[] word = new String[counter];
for (int j = 0; j < counter; j++) {
word[j] = inFile.nextLine();
}
int lengthList = Integer.parseInt(word[0]);
Scanner s = new Scanner(System.in);
Random randomNumber = new Random();
int i = randomNumber.nextInt(lengthList); //picks a word at random. assigns to "word"
String currentWord = word[i];//picks a word at random. assigns to "currentWord"
int turnScore = 10, finalScore = 0;
char input;
String guess ="a";
do { //do loop for whole program looping
turnScore = 10;
do { //do loop for guessing correct
do{
System.out.println("Current Puzzle: " + currentWord);
System.out.println("Current points for this word: " + turnScore);
System.out.println("Enter (g)uess, (n)ew word, (h)int, or (q)uit: ");
input = s.nextLine().charAt(0); //assigns input to first letter entered by user
Character.toLowerCase(input); //puts input to lower case
if(input != 'g' && input != 'G' && input != 'h' &&
input != 'H' && input != 'n' && input != 'N' &&
input != 'Q' && input != 'q'){
System.out.println("Invalid Entry. Please input g, n, q or h only! \n ");
}
} while (input != 'g' && input != 'G' && input != 'h' && input != 'H' &&
input != 'n' && input != 'N' && input != 'Q' && input != 'q'); //end do while loop (ask for input)
if (input == 'g') {
System.out.println("Enter Your guess: ");
guess = s.nextLine();
System.out.println("your guess is: " + guess + "\n\nThe word is: " + currentWord);
if (guess.equalsIgnoreCase(currentWord)) {
System.out.println("You Guessed Correct");
System.out.println("Your Score for this word is: " +turnScore );
finalScore = finalScore + turnScore;
}//end if guess = currentWord
else
{
if (turnScore <= 0)
{
turnScore = 0;
}//end if turn score >=0
else
{
turnScore -= 1;
}//end else turn score minus 1.
System.out.println("Nope, Sorry \n\n");
}//end else guess not = to currentWord.
}//end if user input = G.
else if (input == 'n')
{
i = randomNumber.nextInt();
currentWord = word[i];
turnScore = 10;
}//end new word if
else if (input =='h')
{
turnScore = turnScore/2;
Random ranNum = new Random();
int randomLetter = ranNum.nextInt(5);
char hint = currentWord.charAt(randomLetter);
System.out.println("the Letter at spot " + (randomLetter +1) + " is " + hint);
}//end of if input = h
else if (input == 'q')
{
finalScore = finalScore + turnScore;
System.out.println("Goodbye!");
System.out.println("Final Score: " + finalScore);
System.exit(0);
}//end else if for input = Q.
}while (!guess.equalsIgnoreCase(currentWord));
}while (input != 'q');
System.out.println("Your Final Score is: " + finalScore);
System.out.println("Goodbye!");
inFile.close();
}//End main
}//end class
Your exception is caused by these lines of code:
int counter = 0;
while (inFile.hasNext()) {
inFile.nextLine();
counter++;
}
//inFile no longer has next, will break when the for loop is entered
String[] word = new String[counter];
for (int j = 0; j < counter; j++) {
word[j] = inFile.nextLine();
}
The easy way to fix this is to redeclare the inFile and read from beginning again.
The best way to fix this is to use a dynamically sized ArrayList:
int counter = 0;
ArrayList<String> word = new ArrayList<String>();
while (inFile.hasNext()) {
word.add(inFile.nextLine());
counter++;
}
This also makes your randomizing much more easy since you can do something sneaky with it.
Here's the documentation on ArrayList.
The key, not the solution, to your second question lies add(int index, E element)
There is a way to shuffle on the fly as you read. You should figure that out, and if you get stuck, then come back.
I am creating a program that will determine and print the number of odd, even, and zero digits in an integer from the keyboard. I have tried a few different ways and have gotten the same result with each. I cannot get java to recognize 0 as 0, but only as an even number. Ex. 1005 will give 2 Odds and 2 Evens.
public static void main(String[] args) {
int odd = 0;
int even = 0;
int zero = 0;
int input;
Scanner scan = new Scanner (System.in);
System.out.println("Input an integer please: ");
input = scan.nextInt();
System.out.println("Your number is: " + input);
String x = Integer.toString(input);
for (input = 0; input < x.length(); input++){
char a = x.charAt(input);
System.out.println(a);
Character.getNumericValue(a);
if (a==0){
System.out.println ("+1 Zero");
zero++;
}
else if (a%2 == 0 && a>1){
System.out.println("+1 Even");
even++;
}
else {
System.out.println("+1 Odd");
odd++;
}
}
System.out.println("There are " + odd + " odd numbers!");
System.out.println("There are " + even + " even numbers!");
System.out.println("There are " + zero + " zero numbers!");
}
you haven't assigned Character.getNumericValue(a) to int value .
char a = x.charAt(input);
System.out.println(a);
int y= Character.getNumericValue(a);
if (y==0){
System.out.println ("+1 Zero");
zero++;
}
else if (y%2 == 0 && y>1){
System.out.println("+1 Even");
even++;
}
else {
System.out.println("+1 Odd");
odd++;
}
the Character.getNumericValue(a); method returns an int. It does not implicitly change the parameter (the character variable 'a' in this case).
Thus, you should compare the return value of the getNumericValue method and not the original character.
I'm creating a program for my gui number converter. I want my program to ask user a binary string and if he does not enter a binary number, the program will show him error message and will ask him to enter again. The problem is that I can add restriction to alphabets but when it comes to numbers then it fails or it keeps showing the error message.
import java.util.*;
public class test {
Scanner key = new Scanner(System.in);
String in;
int b;
public test(){
do{
System.out.println("Enter the binary string of 5 numbers");
in = key.nextLine();
int i,j;
char ch;
for (i=0 ; i<=5 ; i++){
b = 0;
ch = in.charAt(i);
j = ch;
if (Character.isDigit(ch) && ch<=0 && ch>=1)
b = 1;
else
System.out.println("Please enter a binary number (1 , 0)");
break;
//b = 1;
}
}while(b != 1);
int c;
c = Integer.parseInt(in);
System.out.println("your number is: " + c );
}
public static void main (String args[]){
test obj = new test();
}
}
ch<=0 && ch>=1 does not do what you think it does. The character codes for "0" and "1" are 48 and 49, so you should check for those instead. Also, your >= comparators are backwards, but that's not really the clearest way to write this code. And since you're comparing for just those two values, Character.isDigit(ch) is redundant.
Try one of these:
ch == 48 || ch == 49
ch == '0' || ch == '1'
Scanner has an overloaded nextInt method that uses a radix
int binaryNumber = scanner.nextInt(2);
1) First logic error here for (i=0 ; i<=5 ; i++) replace i<=5 to i<5
2) change the if else condition like below
if (Character.isDigit(ch) && (ch == '0' || ch == '1'))
{
b = 1;
}
else
{
System.out.println("Please enter a binary number (1 , 0)");
break;
}
