Answer Description:

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.util.Properties;
 
public class StreamToString {
 
    public static void main(String[] args) {
        StreamToString sts = new StreamToString();
       
        /*
         * Get input stream of the data file. This file can be in the root of
         * your application folder or inside a jar file (incase the program is packed
         * as a jar.)
         */
        InputStream is = sts.getClass().getResourceAsStream("/data.txt");
 
        /*
         * Call the method to convert the stream to string
         */
        System.out.println(sts.convertStreamToString(is));
    }
   
    public String convertStreamToString(InputStream is) {
        /*
         * To conver the InputStream to String use the BufferedReader.readLine()
         * method. Iterate until the BufferedReader returns NULL. Each line will *appended to a StringBuilder and returned as String.
         */
        BufferedReader reader = new BufferedReader(new InputStreamReader(is));
        StringBuilder sb = new StringBuilder();
 
        String line = null;
        try {
            while ((line = reader.readLine()) != null) {
                sb.append(line + "\n");
            }
        } catch (IOException e) {
            e.printStackTrace();
        } finally {
            try {
                is.close();
            } catch (IOException e) {
                e.printStackTrace();
            }
        }
 
        return sb.toString();
