How to import text file for dictionary

How to import text file for dictionary

[Trish Cayetano]

I am trying to convert a game in Java to Ada program. 
Please advise how will I call the dictionary text file? Thanks!

This is the Java code of game Text Twist
import java.util.*;
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import javax.swing.event.*;


class WordInfo {

    String originalWord;               // Store the full word here. You must do this.
    int subWordLength;                 // What is the length of each subword here. Again, you need to set this correctly.
    LinkedList<String> subWords;       // The list of subwords of that length.

    LinkedList<String> foundSubWords;  // This is all the words currently found by the user.


    // This will print out all the subwords into a string.
    public String toString ()
    {
	String s = "Subwords of string \"" + originalWord + "\" of length " + subWordLength + ": \n";
	if ( (subWords == null) || (subWords.size() == 0) ) {
	    s += "  NONE";
	    return s;
	}
	for (int i=0; i<subWords.size(); i++) {
	    s += "  " + subWords.get(i) + "\n";
	}
	return s;
    }

} // end-WordInfo

It looks like you inadvertedly posted your Java sources instead of your
Ada sources.

I would suggest looking at the Stream-oriented attributes.
They're what you're going to want to use for serialization/deserialization.
