So I am creating a game where a file of words is given, and the program randomly selects a word from that file, the program must then randomly scramble this word a random number of times and the user will then be given the option to swap letters around by selecting two indexes. I have achieved a lot of the program and I feel like I am on the right track with the swapping, but i just cannot figure it out. We have not learned arrays or anything and my teacher said not to use them. She said I 'need to make a new string by concatenating the parts of the string where these two letters swap their places'. So she wants me to use concatenation, but I just cannot figure how to use that to scramble the word randomly. I also cannot figure out how to allow the user to swap letters by choosing the indexes. I made it so they can select the indexes and it successfully replaces index 1 with index 2, but not index 2 with index 1. Here is my code so far

import java.util.Scanner; import java.io.FileInputStream; import java.io.IOException; import java.lang.Math; public class WordUnscrambler { public static void main (String[]args) throws IOException { FileInputStream fileByteStream = null; Scanner inFS = null; Scanner scan = new Scanner(System.in); String fileWord = '; int random = (int)(Math.random()*12); int userChoice = 0; int userIndex1 = 0; int userIndex2 = 0; boolean userConsent = true; int moveCount = 0; //Opening word file fileByteStream = new FileInputStream('words.txt'); inFS = new Scanner(fileByteStream); //Scanning in random word int i = 0; while(i<=random) { fileWord = inFS.nextLine(); i++; } //Random character variable int randomChar = (int)(Math.random() * fileWord.length()); //This represents the scrambled word, just added q to end for now to represnt it String fileWord1 = (fileWord + 'q'); //While loop of actual game while(userConsent true) { //Printing out setup System.out.println('----------'); //To print index numbers specfic to each word int j = 0; while(j<=fileWord1.length()) { System.out.print(j); j++; } //Printing out options/rest of setup System.out.println('); System.out.println(fileWord1); System.out.println('----------'); System.out.println('); System.out.println('Enter 1 to swap letters.'); System.out.println('Enter 2 to solve.'); System.out.println('Enter 3 to quit.'); System.out.println('); //Scan for user choice userChoice = scan.nextInt(); //If 1 is typed then user can swap if (userChoice 1) { System.out.println('Enter the indexes seperated by a space.'); //User enters indexes they want to swap userIndex1 = scan.nextInt(); userIndex2 = scan.nextInt(); String char1 = ' + fileWord1.charAt(userIndex1); String char2 = ' + fileWord1.charAt(userIndex2); fileWord1 = fileWord1.replaceFirst(char1, char2);//This needs to be fixed //If user succesfully swaps whole word, congratulatory message is displayed and program quits if(fileWord1.equals(fileWord)) { System.out.println('Congratulations! You unscrambled the word project in' + moveCount + ' steps.'); userConsent = false; } } //If 2 is chosen then actual word is displayed and program quits else if (userChoice 2) { System.out.println('); System.out.println(fileWord); userConsent = false; } //if 3 is chosen then program quits else if (userChoice 3) { userConsent = false; } moveCount++; } fileByteStream.close(); } }

I am very sorry for how probably sloppy and hard to read it is, but I am very new to java and coding and really need some help. I'm not sure if I'm using this forum right, i tried to figure it out but I'm getting a little desperate so I apologize if this isn't formatted correctly or maybe in the wrong section. Thank you in advance because absolutely any advice is greatly appreciated.

Recently I had created a Java Program to jumble up words. And I am here to share it with you all. Here's the program. Just copy and paste and compile this program: Java Program: import java.io.; import java.util.; class jumbledupdated static String s,s1='; static char a; static String b; static void mainthrows. Word Jumble Solver. Word Jumble Solver is a small program written in Java which solves word jumble problem. This program is developed for coding challenge from Twice. WordJumbleSolver uses a quick lookup dictionary using the words file generally found at /usr/share/dict/words on un.x type operating systems.

I assume most of you placed the.ocx in the System32 folder. It is pretty simple. The reason the.ocx file is showing up as incompatible, is because it was put in the wrong folder. Here's the solution. Kundli pro software, free download for mobile.

Word Jumble Program Java C++

Welcome to the Ranch
I am afraid that main method is much too long. I think you shou‍ld refactor that code to move nearly all of it out of the main method. I think you shou‍ld have a ScrambledWord object which takes a word as its constructor parameter and later scrambles the field. It can have scramble and unscramble methods; the latter might have a loop where the user enters numbers to swap and stops whenever a number out of range is entered (e.g. < 0).
Don't use file input stream to read a text file. Use file reader and buffered reader, as shown in the Java™ Tutorials (look for buffered streams section).
Avoid doing arithmetic with Math#random(), despite what it says in the Java™ Tutorials. Look at this old discussion, which discusses potential errors about “random” numbers.
Never write true or false. Both are poor style and error‑prone. It is only a matter of time until you write = by mistake, and then your program will start to go wrong.
Not
while(userConsent true) ..
but
while (userConsent) ..
Not
while(userConsent false) ..
but
while (!userConsent) ..
Don't use multiple if statements for menus using 1 2 3 etc. Use switch‑case‑break.
Strings are not intended for changing; the class is immutable. That is why you are finding it so awkward to change the String. I do not think you can use a replace method on a String to achieve what you want.
There are all sorts of design advantages to making things immutable. But many immutable classes have mutable counterparts which are intended for changing. String has a mutable counterpart and here it is, specially designed for changing text rapidly and painlessly. It has methods like insert delete append and replace, so all you need to do is work out the index and the char to replace. You can even chain method calls like this:-
mutableText.insert(index1, char2).insert(index2, char1);
When you have finished with the changes, you can retrieve the text with the toString method. If you need to test for equality during that procedure try
if (mutableText.toString().equals(correctText)) ..
It would have been much easier to achieve that with arrays; you have presumably been told not to use arrays to give you more of a challenge.
How are you scrambling the word? Are you doing that programmatically or asking a user to specify letters to swap?
