Java - Hangman game with StringBuilder. Catching multiple letters in a word

I'm just a beginner in coding and trying to make my 1st project with several classes that is a hangman game. I know there are a lot of threads on the topic here but couldn't manage to find a solution that would work with StringBuilder. I'm stuck with catching multiple letters in the word. Could anyone possibly help?
the method under question is checkAnswer and is below:
public void checkAnswer (){
if (logic.line.indexOf(answer)!= -1){
System.out.println ("You are right! The letter " + answer + " exists");
StringBuilder guessedChar = new StringBuilder(logic.newLine);
guessedChar.setCharAt(logic.line.indexOf(answer), answer);
lettersGuessed = answer +lettersGuessed;
score = score + 1;
System.out.println("Letters guessed: " + lettersGuessed);
System.out.println("Letters missed: " + lettersMissed);
System.out.println("Your score is:" + score);
logic.newLine = guessedChar.toString();
System.out.println(logic.newLine);
}}
Below is the full code:
main class
public class Main {
public static void main(String[] args) throws Exception {
Logic act = new Logic();
Game game = new Game();
act.getListOfMovies();
act.CodedLine();
do { game.input();
game.checkCondition();
game.checkAnswer();
game.checkScore();
} while (game.lettersGuessed.length() != act.line.length() && game.score!= -10);
}}
Class Logic
public class Logic {
static String line;
static String newLine;
public String[] listOfMovies;
public Scanner fileScanner;
public Logic() {
}
public String getListOfMovies() throws Exception {
File fileWithMovies = new File("MoviesList.txt");//file access
Scanner fileScanner = new Scanner(fileWithMovies);//file scan
while (fileScanner.hasNext()) { // while there is a next line
line = fileScanner.nextLine();
String[] listOfMovies = new String[24]; //introduce array
for (int i = 0; i < listOfMovies.length; i++) { //
listOfMovies[i] = fileScanner.nextLine();
}
int random = (int) (Math.random() * listOfMovies.length); //get random number
for (int i = 0; i < line.length(); i++) { //get random movie
if (Character.isLetter(line.charAt(i))) {
line = listOfMovies[random];
System.out.println(line);
}
return line;
}
return line;
}return line;
}
public String CodedLine() {
newLine = line.replaceAll("[a,b,c,d,e,f,g,h,i,j,k,l,m,n,o,p,q,r,s,t,u,v,w,x,y,z]", "_");
System.out.println(newLine);
return newLine;
}}
Class Game
public class Game {
char answer;
Logic logic = new Logic();

String lettersMissed = " ";
int score = 0;
public char input () {
Scanner inputScanner = new Scanner(System.in);
System.out.println("Type in your guess");
answer = inputScanner.next().charAt(0);
System.out.println("Your guess: " + answer);
return answer;
}
public void checkCondition (){
if (logic.line.indexOf(answer)==-1){
System.out.println("You are wrong. The letter " + answer + " does not exist");
lettersMissed = answer + lettersMissed;
score = score - 1;
System.out.println("Letters guessed: " + lettersGuessed);
System.out.println("Letters missed: " + lettersMissed);
System.out.println("Your score is:" + score);
}}
public void checkAnswer (){
if (logic.line.indexOf(answer)!= -1){
System.out.println ("You are right! The letter " + answer + " exists");
StringBuilder guessedChar = new StringBuilder(logic.newLine);
guessedChar.setCharAt(logic.line.indexOf(answer), answer);
lettersGuessed = answer +lettersGuessed;
score = score + 1;
System.out.println("Letters guessed: " + lettersGuessed);
System.out.println("Letters missed: " + lettersMissed);
System.out.println("Your score is:" + score);
logic.newLine = guessedChar.toString();
System.out.println(logic.newLine);
}}
public void checkScore (){
if (score == -10) {
System.out.println("The game is over! You lost..."); }}}

//Create list for index
ArrayList<Integer>answerIndexList=new ArrayList<Integer>();
//get char index
for (int i=0;i<logic.line.length();i++){
if(logic.line.charAt(i) == answer){
answerIndexList.add(i);
}
}
//replace index with answer
for(int i=0;i<answerIndexList.size();i++){
guessedChar.setCharAt(answerIndexList.get(i), answer);
}
logic.newLine = guessedChar.toString();

Not gonna solve it for you, not what this site is for, but suggestions:
check this method - basically you tell it where the indexOf should start searching. At first you start with 0, then if you find a result you start at foundResultIndex + 1, put it all in a loop and voila.
word: batman, guess: a
int startAt = 0;
int foundResultIndex = "batman".indexOf('a', startAt) // 1
startAt = foundResultIndex + 1;
foundResultIndex = "batman".indexOf('a', startAt) // 4
...
don't keep so much state in your programs, especially static like in Logic class. Your getListOfMovies is perfect example, you are already returning a result, why keep it in some line variable? Use the returned result instead.
the replaceAll is funny, do this instead line.replaceAll("[a-z]", "_");

Program won't continue when pressing enter. How do I fix this error?

I am working on a rock paper scissors homework assignment for my java class. I am done with the program and I compiled it successfully. I ran the file and it looked like it was working. It gives me the menu and I choose a variable, R for example, and when I press enter it doesn't do anything but go to the next line. I press enter again and it gives me an index out of bounds error which I assume is because the second time it didn't have a variable to use. How do I get the program to move forward? The program is supposed to play five times then return a winner. Thanks in advance.This image is what I get when I run the program and press enter twice
package Rock;
import java.util.Scanner;
public class RPSG {
public static void main(String[] args) {
String[] computerHandArray = {"R","P","S"};
String computerHand ="", thisWinner="", theFinalWinner="";
int index=0;
int timesIWon=0;
int timesComputerWon=0;
Scanner in = new Scanner(System.in);
System.out.println("\tMenu\n\n(R) Rock\n(P) Paper\n(S) Scissors" + "\n\nEnter Your Hand (R, P, or S): ");
for (int i=0; i<5; i++) {
String myHandString = in.nextLine();
String myHand = myHandString.substring(0,1);
myHand = myHand.toUpperCase();
index = (int)(Math.random() * 10) % 3;
computerHand = computerHandArray[index];

if(thisWinner.equals("ME")){
timesIWon++;
}

}
}
if(timesIWon == timesComputerWon)
theFinalWinner = "TIE";
else if(timesIWon > timesComputerWon)

else if(timesComputerWon > timesIWon)
theFinalWinner = "COMPUTER";
System.out.println("I won :" + timesIWon);
System.out.println("I won :" + timesComputerWon);
System.out.println("The Final Winner after 5 games is:" +theFinalWinner);
}
private static String theWinnerofOneGame(String myHand, String computerHand){
String theWinner = "Tie";
if(myHand.equals(computerHand)) {
theWinner = "Tie";
}
else if(myHand.equals("R")) {
if (computerHand.equals("P")) {

}
}
else if(computerHand.equals("S")) {

}

You print the prompt for input only once, i.e. before the for loop. Now when you enter your first input, the content of the loop will be executed. Because you don't print anything inside the loop, there is no prompt for the next round. After you press enter a second time, the in.nextLine() returns an empty string and subsequently, the substring method throws the exception.
You should probably do something like this (note the marked lines):
System.out.println("\tMenu\n\n(R) Rock\n(P) Paper\n(S) Scissors" + "\n\n");
for (int i=0; i<5; i++) {
> System.out.println("Enter Your Hand (R, P, or S): ");
String myHandString = in.nextLine();
String myHand = myHandString.substring(0,1);
myHand = myHand.toUpperCase();
index = (int)(Math.random() * 10) % 3;
computerHand = computerHandArray[index];
thisWinner = theWinnerofOneGame(myHand, computerHand);
if(thisWinner.equals("ME")){
timesIWon++;
> System.out.println("You won.");
} else if(thisWinner.equals("COMPUTER")) {
timesComputerWon++;
> System.out.println("The computer won.");
}
}
And even better, check if the input of the user is valid before computing the substring.

single dimensional array battleship code

I am beginner in java. I was trying to emulate the single dimension array battle ship code from heads first java book. The code is not failing, but I am not able to make it work properly.
Example: [1,2,3] is the array which contains the location of the battle ship. If I guess any number except 1, it is displaying as miss. But if I guess it as 1 three times (length of battleship) in a row I am making it as kill. I am not able to figure out this issue.
Could you please help me out here. The code is posted below:
package battleship;
public class battleship {
public int[] battleship = new int[3];
public int numofhits = 0;
String result = "miss";//instance variables complete
//setter method to initialize the array which holds the battle ship location
public void setbattleshiploc(int startpos) {
int i = 0;
for(i = 0; i < battleship.length; i++) {
battleship[i] = startpos + i;
System.out.println(battleship[i]);
}
System.out.println("initialized array is: " + java.util.Arrays.toString(battleship));
}
//getter method to print the set battleship array
public int[] getbattleshiploc() {
System.out.println("Battleship array is: " + battleship);
return battleship;
}
//checking whether user guess inside the battleship array location
public String guessloc(int guessnum) {
//int i = 0;
for(int cell : battleship) {
System.out.println("Guessed number is: " + guessnum + " array element: " + battleship[cell]);
System.out.println("cell: "+ cell + " ,battleship[cell]: " + battleship[cell] );
if(cell == guessnum) {
numofhits++;
if(numofhits == 3) {
result = "kill";
return result;
}//if the hits are 3 then return kill indicating that no more battle ship is available
else {
result = "hit";
return result;
}//end inner else
}//end outer if
else {
//numofhits++;
result = "miss";
return result;
}//end the if-else
}//end for loop
return "finished";
}//end function guessloc
}//end class
package battleship;
import java.util.Scanner;
public class gamelauncher {
public Scanner[] reader;
public static void main(String[] args) {
String result = "miss";
int numofguess = 0;
//int loopnum = 0;
battleship launchgame = new battleship();//launch the game
int startpos = (int) (Math.random() * 5);//generate random number between 0-4
//int[] location = {startpos, startpos + 1, startpos + 2};//initialize three consecutive array element
launchgame.setbattleshiploc(startpos);//set the array as the battleship location using setter
//display the battleship position
System.out.println("Battle shipt positions are: " + startpos +" ," + startpos+1 + " ," + startpos+2);
System.out.println("the battle ship array is: " + launchgame.getbattleshiploc());
//int[] battleshiplocation = launchgame.getbattleshiploc();
System.out.println(java.util.Arrays.toString(launchgame.getbattleshiploc()));
while(result != "kill") {
Scanner reader = new Scanner(System.in); // Reading from System.in
System.out.println("Enter a number: ");
int guess = reader.nextInt(); //get the user input integer
//reader.close();//close the scanner
//loopnum++;
numofguess++;
if(guess < 0 || guess > 7) {
System.out.println("Maximum space available is 7 units(0-6) and battleship length is 3 units, Please provide the location accordingly");
continue;
}//close if loop and go to the loop execution if the guess is not within the limits
else {
result = launchgame.guessloc(guess);
System.out.println("response from guessing method: " + result);
//get the status(hit/miss/kill) back from guess location method
if(result == "kill") {
System.out.println("We have destroyed all the parts of battle ship and it took " + numofguess +" guesses" );
break;//get out of the loop as we have destroyed everything
}//end kill
else if(result == "hit") {
System.out.println("You have destroyed " + launchgame.numofhits+" parts of batlleship, please continue");
continue;
}
else {
System.out.println("It's a miss dumbo, try again");
continue;
}
}//end outer else statement
}//end while loop
}//end main method
}//end class

I can help you by giving you this function a bit changed. Please try to fix the rest of your code on your own. It will give you important experience.
public String guessloc(int guessnum) {
for(int i=0;i<battleship.length;++i) {
if(battleship[i] == guessnum) { //it's a hit
battleship[i] = -1; //you cant hit it again, so change it
if(++numofhits == 3) {
return "kill";
}else
return "hit";
}
}
return "miss"; //miss should be outside of the for loop
}

I believe the problem is that when you are comparing Strings u are using == instead of .equals() so your code should like like this:
if(result.equals("kill"))

I'm having tons of issues with this program. I can't get my string comparisons to work and I have several infinite loops that I'm not sure how to fix. I would appreciate a fresh set of eyes to show me what I'm missing, I've been staring at this for 3 days and I keep skipping over my errors. The program needs to pick a random word from the given text file, scramble up that word, then have the user guess what the original word was. Hints should display what letter is at a given random position within the word.

Right out of the gate, I had a compilation error because pickedWord is being referenced outisde of the if statement in which it was declared. So, by the time it got to if (guess.equals(pickedWord)), the compiler doesn't know what pickedWord is.

The first thing that popped out at me was the if/else ladder.
String scrambledWord = sb.toString();
if (scrambledWord.equals(pickedWord)) {
System.out.println("The words match");
allTrue = false;
}
System.out.println("Current puzzle: " + scrambledWord);
System.out.println("Current points for word " + wordScore);
System.out.println("Enter (g)uess, (n)ew word, (h)int, or (q)uit: ");
responseLetter = in.next().charAt(0);
}
Notice how you close your if statement before getting a response for responseLetter. This means, your loop condition: "while game == true" isn't properly being evaluated.
