I am trying to take in user input and storing it in a text file, I was able to take in the input and storing it but now i am trying to display that input in a JOptionPane
window. Can someone please help me. I am new on stackflow and this is my first post.
/*Here i am taking in user input and storing it in a file called "dictionary.txt".*/
public static String addNewWord()throws IOException
{
String newWord = "";
newWord = JOptionPane.showInputDialog(null, "Enter the word you want to add to your dictionary.");
FileWriter aDictionary = new FileWriter("dictionary.txt", true);
PrintWriter out = new PrintWriter(aDictionary);
out.println(newWord);
out.close();
aDictionary.close();
return newWord;
}
/* Now i am trying to read "dictionary.txt" and display it using JOptionPane*/
public static String listDictionary()throws IOException
{
FileReader aDictionary = new FileReader("dictionary.txt");
String aLineFromFile = FileReader;
JOptionPane.showMessageDialog(null, aLineFromFile);
aDictionary.close();
return aLineFromFile;
}
You should use a BufferedReader
to read the data back from the file:
public static void listDictionary()throws IOException
{
BufferedReader br = new BufferedReader(new FileReader("dictionary.txt"));
String aLineFromFile = null;
while ((aLineFromFile = br.readLine()) != null){
JOptionPane.showMessageDialog(null, aLineFromFile);
}
br.close();
return;
}
