Thread: How to save a word in a text file

This part of the code searches for every word in the text file and saves it to an ArrayList. It searches for the word if its valid of not.

How can I offer a list of similar words when the word that the user inputs is not in the dictionary. Also I want it to prompt the user to accept the word or enter a replacement that gets saved in the dictionary.

package spellChecker.project1;
 
import java.io.FileNotFoundException;
import java.io.FileReader;
import java.util.ArrayList;
import java.util.List;
import java.util.Scanner;
 
public class SpellChecker {
 
	public static void main(String[] args) {
 
		Scanner scanner = new Scanner(System.in);
 
		System.out
				.println("Enter the path of the dict txt file(C:/Users/Stalin/Desktop/dictionary.txt):");
 
		String path = scanner.nextLine();
 
		String myFileName = path;
 
		int count = -1;
		int count2 = 0;
 
		List<String> words = new ArrayList<String>();
 
		try {
			FileReader myFile = new FileReader(myFileName);
			Scanner scanMyFile = new Scanner(myFile);
 
			while (scanMyFile.hasNext()) {
				String line = scanMyFile.next();
				// System.out.println(line);
				words.add(line);
				count++;
				//System.out.println(words.get(count));
			}
			scanMyFile.close();
			// System.out.println(count + " words");
		} catch (FileNotFoundException e) {
			e.printStackTrace();
		}
 
		System.out.println("Please enter a word:");
 
		String typeword = scanner.next();
 
		for (int i = 0; i < count; i++) {
			String word = words.get(i);
			// System.out.println(word);
			if (typeword.equals(word)) {
				System.out.println(typeword + " is a valid word in the dict.");
			}
			if (!typeword.equals(word)) {
				count2++;
			}
			if (count == count2) {
				System.out.println(typeword
						+ " is an invalid word in the dict.");
			}
		}
 
	}
}

thank you guys

yeah I'm searching on the Internet to see if I find anything. What about saving a word that the user inputs to the dictionary file? How can I do this?

Looks like there are lots of algorithms that you can use to check for similar words. See Check how much a String sounds like another one in Java - Stack Overflow (found using Internet search term "java similar word") for a discussion and suggested algorithms/implementations on this.

Since the dictionary file is a plain text file, saving a word inputted by a user would involve (re)writing all existing words together with the new word into the same file. See Reading, Writing, and Creating Files (The Java™ Tutorials > Essential Classes > Basic I/O) for details on writing into a file.
