Read text file with InputStream of getClass().getResourceAsStream()

This example show how to read text from InputStream of getClass().getResourceAsStream(src). Where src is the text file inside package.

package java_readfile;

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.util.logging.Level;
import java.util.logging.Logger;

public class Java_ReadFile {

    String src = "song.txt";

    public static void main(String[] args) {

        Java_ReadFile java_ReadFile = new Java_ReadFile();
        java_ReadFile.readFile();
    }

    private void readFile() {
        StringBuilder stringBuilder = new StringBuilder();

        InputStream inputStream = getClass().getResourceAsStream(src);

        if (inputStream == null) {
            System.out.println("inputStream == null");
        } else {
            BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(inputStream));
            
            try {
                String line;
                while ((line = bufferedReader.readLine()) != null) {
                    stringBuilder.append(line).append("\n");
                }
                System.out.print(stringBuilder.toString());
            } catch (IOException ex) {
                Logger.getLogger(Java_ReadFile.class.getName()).log(Level.SEVERE, null, ex);
            }

        }

        System.out.println("- Finish -");
    }
}
